Icebound Underworld

Icebound Underworld is a dungeon located at the Temple of Shadows, north of Dawnglory. Players can also teleport to the dungeon via the Illusion Stone in Archosaur for a fee of 20,000 silver coins. It is available for players who have reawakened twice, are level 100, and have a Boundary level of Shifting Sky I. Through the dungeon, players can farm items such as Dragon Orbs, Star Chart materials, Glyphs and equipment such as Cube Necklaces and Nirvana Gear. Icebound Underworld is a required dungeon for Faction Goals for the Faction Base. The objective of the goal is to kill the 10th boss, Lord of Disaster Soulshriek.

To enter, players will need a Dark Jade Soulstone, which can be acquired from completing the This War o' Mine Primal Quest once per day. The Dark Jade Soulstone lasts for 24 hours and will expire if not used.

Overview
The dungeon has a time limit of 999 seconds (or 16 minutes and 39 seconds), which can be seen on an interface on the player's screen. On this interface there is also the stage number the squad is on (if any), along with the prizes the squad has earned thus far. The timer does not start running down until the squad leader starts the dungeon.

To start the dungeon, the squad should run down the corridor and then jump off the edge into the water below. The squad leader will see a window appear with a Start button on it, which will start the challenge. The squad leader should press this button once the squad is in range and ready to begin. The timer will begin running immediately after the button is pressed.

The Icebound Underworld has a total of 19 stages. Each stage consists of a boss fight, which is done in order; the bosses fought are not in a random order. Each boss can take a maximum of 1,000,000 damage per hit to prevent them from dying too quickly. If the squad reaches the final boss, Underworld Lord Chenzi, they can kill him an infinite amount of times for extra rewards as long as the timer is still running. When the timer runs out the boss currently being fought will disappear, and a window will appear showing the prizes the squad has earned for each player.

Daily Quest
Each day, upon entering Icebound Underworld, players will receive a quest named Icebound Melody. To complete this quest, players will need to kill Lord of Disaster Soulshriek, the 10th boss in the dungeon. Completing this quest will give the following Star Chart rewards:
 * Starglade Chest x1
 * Astrobana Pearl Lv1 x4
 * Astrospira Pearl Lv1 x4
 * Nebula Dust Orb x2

Greedy Devourer Senmai (First Boss)
Greedy Devourer Senmai is the first boss encountered in the Icebound Underworld. Shortly after the battle starts the boss will purge the whole squad and a Mirror of Devourer will spawn.

Butcher Baron Wenham (Second Boss)
Butcher Baron Wenham is the second boss encountered in the Icebound Underworld. Purple circles will appear on the ground which deal constant damage to players inside them, and also applies an increase damage taken debuff to them. Players should avoid these circles.

Grim Phantom Loyan (Third Boss)
Grim Phantom Loyan is the third boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. An on-screen message will appear saying "Joys and Sorrows will be released in 10s. Please gather." At this point players should stand together at close range. Afterwards, another on-screen message will appear saying "Players attack be Living Bomb will explode in 10s. Please stay away from the crowd". At this point several players will have a bomb debuff on them, indicated by a glowing aura above their head. These players should move away from the group. When the bomb's timer runs out it will kill any nearby player.

Molten Shield Blazehowl (Fourth Boss)
Molten Shield Blazehowl is the fourth boss encountered in the Icebound Underworld. Two circles will appear on the ground - a red circle with swords in the middle, and a yellow circle with spears in the middle. A certain amount of players must stand in both circles to solve a math problem within 20 seconds. The math problem is mathematical, and usually in the form of [Players in the sword aura] x [Players in the spear aura] = number. For example the on-screen message may say "Within 20s: [Players of Sword Aura] x [Players of Spear Aura] =6", which means that 2 players should stand in one aura while 3 players should stand in another aura, as 3 x 2 = 6. Other players should move outside of the auras to prevent being counted. If this is not done correctly, the boss will heal itself to full health.

As the circles do overlap, it is possible to have players stand in the overlap area to count for both areas. Using the example from before, it would be possible for 2 players to stand in the overlap, and 1 player to stand in one of the circles.

Lord of Grief Mistblade (Fifth Boss)
Lord of Grief Mistblade is the fifth boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged.

Drops
Lord of Grief Mistblade drops a total of 10 items. The drop chances are as follows:
 * Mirage Celestone: 30%
 * War Avatar Pack C: 70%

Soul Devourer Senjin (Sixth Boss)
Soul Devourer Senjin is the sixth boss encountered in the Icebound Underworld. Upon spawning, two other monsters will spawn named Souleater Zor and Souleater Yul, and Soul Devourer Senjin will be immune to all damage. Souleater Zor and Souleater Yul must be killed at the same time in order to remove the immunity buffs from the main boss. The Souleaters will each have a 40 second buff that makes them immune to certain damage - one will be immune to physical damage, while the other will be immune to elemental damage. After the buffs wear off, they will swap to have the opposite immunities, and so on and so forth.

On occasion an on-screen message will appear saying "(Player Name), betray those so-called teammates!". The player whose name was in the on-screen message will have a blue aura around them and they will be unable to attack. Any players within this aura will get an aura of their own, which can further spread to other players in the squad. If a player's name is in the on-screen message they should move away from the rest of the squad until the aura goes away.

Cursed Grudge Eurion (Seventh Boss)
Cursed Grudge Eurion is the seventh boss encountered in the Icebound Underworld. Upon starting the fight some players in the squad will have a Dark Link buff added to them as well as increased attack speed and channeling buffs. If these players attack the boss then it will heal its health, so they should refrain from attacking until the buff wears off. Cold Jade Crystals will also spawn on certain players which will freeze them, preventing them from attacking. The Cold Jade Crystals will not spawn on those with the Dark Link buff on. Other players in the squad can attack and kill the Cold Jade Crystals to free their fellow squad members.

After some time has passed, an on-screen message will appear announcing that Cursed Grudge Eurion will cast Djinn's Waltz in the next 10 seconds. It is not known what it does.

Venomous Feather Enkros (Eighth Boss)
Venomous Feather Enkros is the eighth boss encountered in the Icebound Underworld. The boss cannot be damaged unless players are less than 8 meters away from it, so players will have to attack it from close range. The boss also has an aura around it which will damage players over time, which they will be forced to stand in in order to deal damage to the boss. At times half of the area will be covered with a green light, which will deal damage to players if they do not move outside of it.

Bloodthirsty Beast Churial (Ninth Boss)
Bloodthirsty Beast Churial is the ninth boss encountered in the Icebound Underworld. Throughout the fight, one player at random will have a Stalker debuff added to them for 12 seconds, indicated by an eye above their head. The boss will target this player and begin to move towards them. The marked player should run away from the boss, being careful to not stand in the red cone in front of it. If they let the boss walk up to them and attack them then it will begin to heal itself. The target will change to another random player in the squad after the Stalker debuff has run out.

Lord of Disaster Soulshriek (Tenth Boss)
Lord of Disaster Soulshriek is the tenth boss encountered in the Icebound Underworld. This boss is required for both the Icebound Underworld daily quest and Master Bounty Hunter quests. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. It will also constantly purge the squad's buffs and cast a Mana drain debuff on them.

Drops
Lord of Disaster Soulshriek drops a total of 20 items. The drop chances are as follows:
 * Mirage Celestone: 25%
 * War Avatar Pack C: 50%
 * Benevolence Seal: 5%
 * Strongwind Badge: 15%
 * Garan Stone: 1.5%
 * Kunwoo Blade: 3.5%

Sylvan Keeper Lortan (Eleventh Boss)
Sylvan Keeper Lortan is the eleventh boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. Upon starting this boss he will buff himself with a Soul of Vengeance-like reflect buff, which reflects a deadly amount of physical damage to players who attack him and cannot be purged normally. The reflect can be bypassed by using immunity skills or physical immunity skills such as Expel or Psychic Will. In addition an on-screen message will appear on occasion indicating that non-barbarians who are standing in front of the boss will be debuffed. If non-barbarians are in this range they will be stunned and given a curse debuff which increases the damage they take.

Three other monsters will spawn around the area named Explosive Minion. These monsters are immune to damage and will completely drain a player's Chi if they are too close. When a player with Chi attacks one from close range a timer will appear above the player's head, counting down from 10. The timer will not appear if they do not have a minimum of two sparks (200 Chi). The player must then stand right at Sylvan Keeper Lortan before the timer reaches 0. If they do this successfully then the reflect buff will disappear allowing the squad to attack the boss without being harmed. The boss can potentially rebuff itself with the reflect buff, so this step should be done repeatedly.

Thunderous Avatar Rokran (Twelfth Boss)
Thunderous Avatar Rokran is the twelfth boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. The boss will also be immune to physical and elemental damage. A Thunder Trap will appear, which can be dug to unleash a Thunderball area on the ground. If the boss is lured to this area then its buffs will be removed, allowing the squad to deal damage to it. 10 seconds after the Thunder Trap appears the boss will AoE the squad. This process repeats itself throughout the battle.

Necrotic Doom Angtus (Thirteenth Boss)
Necrotic Doom Angtus is the thirteenth boss encountered in the Icebound Underworld. It will curse the player that is standing closest to it, which can stack. If the curse stacks up to 5 times then that player will die, making the boss a threat particularly to classes who attack from melee range. It will also occasionally AoE the squad and stun them for a short period of time.

Underworld Judge Ostav (Fourteenth Boss)
Underworld Judge Ostav is the fourteenth boss encountered in the Icebound Underworld. An on-screen message will appear stating "(Player Name), you're guilty!" after which the player whose name is in the message will have a bomb placed on them. A red circle will also appear underneath them. This player should be purified as soon as possible or the bomb will explode and kill the rest of the squad, even if they are not standing in the red circle. The players that are standing inside the red circle when the bomb-carrying player is purified will be paralyzed for a short amount of time.

Night Templar Kivon (Fifteenth Boss)
Night Templar Kivon is the fifteenth boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. It will constantly purify itself of debuffs by transferring them to other players. The boss will also AoE the squad and drain all of their Chi constantly. The boss will heal itself if a player dies.

Drops
Night Templar Kivon drops a total of 24 items. The drop chances are as follows:
 * Mirage Celestone: 33.33%
 * War Avatar Pack C: 62.5%
 * Dragon Orb Ocean Shard: 4.16%

Magma Serpent Honga (Sixteenth Boss)
Magma Serpent Honga is the sixteenth boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. It cannot be damaged unless players are less than 8 meters away from it. A barbarian must tank the boss as it will constantly kill any other class that has aggro. The deadly attack can be avoided by non-barbarians if they use well-timed immunity skills.

Five Fireprime Hounds will also spawn around the boss, all immune to damage and inactive. Eventually one of these hounds will become active, lose its immunities, and will begin to kill off squad members at random, indicated by an on-screen message. The hound should be killed quickly to prevent it from killing squad members, and can only be damaged if players are less than 8 meters away from it. As the battle progresses other hounds will also become active and should be killed as soon as possible.

Inferno Yama Sanhro (Seventeenth Boss)
Inferno Yama Sanhro is the seventeenth boss encountered in the Icebound Underworld. It will constantly deal damage to players near it, and on occasion will make itself untargetable to the squad. Players can continue to deal damage to it in this state if they have a constant AoE running, such as Dragon's Breath or Yataghan Vortex. After some time, the boss will disappear and several clones will spawn and AoE the squad. These clones must be killed in order for the original boss to spawn again. The clones will keep multiplying and they will get progressively stronger. When the boss respawns it will appear with much less health than its first version.

Bodyfall Scavenger Namina (Eighteenth Boss)
Bodyfall Scavenger Namina is the eighteenth boss encountered in the Icebound Underworld. Five pools will appear around the boss, with a light yellow circle in the middle of each. These pools will get bigger over time and will damage players if they stand within them. The pools will reduce in size and disappear if a player stands in the light yellow circle within the pool, though the player will constantly take damage while doing so. These pools will respawn again over time.

Occasionally a cone will spawn facing towards a random player in the squad, which will kill anyone within its range. Players can evade death by using a well-timed immunity skill.

Underworld Lord Chenzi (Nineteenth Boss)
Underworld Lord Chenzi is the nineteenth and final boss encountered in the Icebound Underworld. The boss begins with an 8 second heal over time as well as defense level buffs and a maximum health buff, which can be purged. A barbarian should tank the boss as he will perform an attack indicated by a red rectangular area in front of him, which will kill non-barbarians that are within the area.

An on-screen message will also appear stating that the boss will cast Oblivion and should be interrupted. Players can use channel-interrupting skills to prevent the attack from occurring. If players fail to interrupt the boss, the Oblivion attack will kill the whole squad. Players using the Genie skill Faith or barbarians using ΨCornered Beast with a Sanguine Glyph effect can avoid Oblivion's damage. At certain intervals players will be affected by Bleed and Burn DOTs. Dog monsters will spawn and attack random players. These dogs cannot be killed so players will have to tank the damage or run around to avoid the damage.

Upon his death, the boss will reappear allowing the squad to kill him repeatedly for extra rewards until the dungeon's timer runs out. Every time the boss respawns it will have more Health than the previous one, the DOTs will deal more damage and more dogs will spawn.

Drops
Underworld Lord Chenzi drops between 10 and 30 items. The drop chances are as follows:
 * Golden Glyph Lv1: 18.66%

 * Stages 10 - 19: 1 Underworld Goldstone for each stage completed

When the time limit runs out, a window will appear showing the prizes that the squad has earned for each player. Players can redeem their rewards by clicking the "Receive reward" button. If they close this window or cannot click the button, they can leave the dungeon and receive their prizes from Icebound Messenger Eli, located at the entrance of the dungeon (741, 933).
