Shambler

The Shambler is an Eldritch mini-boss that drops ancestral trinkets when killed. The Shambler appears as a hallway fight witha very small chance in total darkness or when a Torch is used in a Shambler's Altar (which instantly reduces light to 0).

Behavior
The party will always be surprised when encountering a Shambler. If summoned from an altar, the Shambler with automatically bring the torchlight down to 0 and will prevent the party from lighting torches while fighting it. If summoned but then ran away from, the Shambler will appear again as the next encounter. Don't summon it unless the party is ready to kill it. Due to a very low speed, he most likely will act last, using his bleed or blight attack and summoning 2 Tentacles. Unlike Shambler himself, Tentacles have a very high speed, they are very likely to take actions before the party, applying a strong buff to themselves. If one or both of Tentacles are killed, Shambler will re-summon them, if both left alive he has a chance to use Stentorious Lament, messing party's formation.

Abilities
* Summoning will occur regardless of the ability lands or not.

Strategy
Shambler is very strong, stronger than some bosses. Most of the times it would be a right choice to pass on the opportunity to fight him. Nevertheless, if you decide to summon him, its better to return after you completed the quest objective to do so, because your party most likely will be in no condition to continue the expedition after the encounter with the Shambler.

When dealing with Shambler it's important to finish the fight as soon as possible. The general strategy is to kill Tentacles and stun the Shambler to prevent him from re-spawning them. If you dont have enough damage or reliable stun to do that, leave 1 Tentacle alive, the Shambler might use the Stentorious Lament. It will shuffle your party but not summon a Tentacle. A variation of the Marking Party, however, can ignore the Tentacles and finish the Shambler in 2-3 turns. High Bleed and blight resistance is encouraged.

When assembling a party to hunt the Shambler specifically, consider the following classes: the Abomination, due to his high speed, can kill both Tentacles with Rake before they buff themselves; the Crusader can also take care of them with his Zealous Accusations; The Hound Master can reduce Shambler's PROT, Bounty Hunter can land a lucky stun, Occultist does increased damage vs. Eldritch. All of them and the the Arbalest have a marking synergy.

Please note, that champion difficulty Shambler is much stronger than his previous iterations.

Trivia

 * Despite that The Shambler takes up 2 Ranks during a fight, it leaves a normal Corpse after it is killed instead of a large one.
 * As of the Inhuman Bondage update, the Shambler will physically drag the party into another dimension. The area resembles a violet galaxy and functions the same as Pitch Black.
