Crucible Challenge is a solo instance available to level 46+ players. It can be accessed from the Marchutan Priory in Pandaemonium for Asmodians or Kaisinel Academy in Sanctum for Elyos. You can re-enter after 22 hours. Resurrection skills will not work inside the instance. If you die, you can only reenter the fight if you have a <Worthiness Ticket> obtained after the first stage.
Round 1
Backing up at the beginning of the round will allow the opportunity to fight the Malodors one at a time without aggroing the others. After killing two, an additional two will spawn. Watching aggro here will make it fairly easy to fight these one at a time as well. Rest between fights if needed.
Round 2
Kill Grissil, who has a chance to spawn Grissil's Branch(es) when under 25%. Either kill the add(s) or continue to kill Grissil. The Branch(es) will despawn when Grissil is dead. A chest will appear containing 1 Worthiness Ticket at the end of the round.
Round 1
Both options of NPCs will attack each other. While it may seem like a good idea to let them kill each other, it's not. Get as much damage on them before they turn their attention. Aggro Tirratirra first and get her close to death, then chose one of the two birds to fight. The birds will finish her off. If fighting the kerubs, immediately attack one to delay them getting their attack buff. Kill one and then the other.
Bonus Round
Keep Poppy on the Run alive until the timer expires. Poppy runs randomly around while cooks try to catch him for their next meal. Killing or aggroing each cook as they appear prevents them from attacking Poppy. Alternatively, healing classes can heal Poppy through the damage. After saving him, Poppy's Present appears and provides a reward.
Round 1
Attacking the <Aether Barrel> or <Meat Barrel> will lure and distract the spirits or karnifs. Then it is possible to pull them one at a time. Destroying the Barrel when it reappears continues to distract the NPCs. Shortly after killing three, the boss will appear. Whihazad cast silence, so be ready with a healing potion to dispel it. Head Greentooth has hard melee attacks, so healing or potions may be helpful.
Round 2
Fiery Gomju will appear, but waiting a moment while he AoEs to kill the six Poison Deadly Drakuni will avoid early damage. After 50%, he may cast a shield and does not attack while the shield is up. The shield blocks all damage except for DoTs. He may also spawn two Gomju's Minions before or after casting his shield.
Round 1
The spawns will be in a T shape and can easily be pulled one at a time. Kill the boss last, as he will call in the other mobs otherwise.
Round 2
Kaliga will use stuns, pulls and summon two bloodwings to help him. Hamerun will use debuffs.
Bonus Round
There is a choice of three chests. Two contain Crucible Insignias. One will spawn a pet. The first set of chests may contain 1 insignia, 10 insignias or the Pet Kirca. The second set may contain 2 insignias, 18 insignias or the Pet Manduru. The last set of chests may contain 3 insignias, 26 insignias or a Pet Starcrab. If you get all three pets, one last chest will appear that contains 250 Crucible Insignias.
Round 2
A merchant NPC will spawn. Berus or Genoti use 22pxGodstone Pride which raises their attack speed and 22pxEio's Tears to lower your attack speed. At 50% he uses 22pxOrissan's Blood to poison you for 15 seconds. Angparinerk or Paepaerunerk will self buff and at 50% uses a stun than cannot be removed. He will also use a self heal to bring his HP back up to 50% if not defeated fast enough. Bustant or Roskva will use self attack buffs and an attack speed buff when under 50%. Running attacks are useful here. They can self heal bringing HP back to 50% if not defeated fast enough.
Round 1
Vanktrist Spacetwine uses 22pxYoung Space Twist and 22pxVoid Flame to stun and damage. At 75% he uses 22pxGravitational Shift to slow your speed. At 50% he uses the Young Adrift skill for damage. At less than 50% he summons three vortexes that are easily defeated. Vanktrist is able to be CC'd, so use that to buy time to heal or get mana if needed.
Bonus Round (Quest is required to enter)
After five successful defeats of Vanktrist, a rift portal appears which allows access the bonus area. You will either fight a) the Tiamat Assassin for the rewards of fluxes, Balic items, enchantment stones, or manastones, or b) an opposing faction enemy for fluxes, enchantment stones, manastones or Crucible Challenge Godstones.
If Poppy on the Run survives the onslaught of Dukaki Cooks in the bonus round, you will get a Poppy's Present chest. The chest will reward one of the following:
