The Fanatic

"Madness can take many forms, but none so contemptible as man's belief in a mythology of his own making. A world view buttressed by dogmatic desperation invariably leads to single-minded fanaticism, and a need to do terrible things in the name of righteousness. This man is an animal - rabid, destructive, and incapable of nuanced understanding. He. must. be. put. down. Loading_fanatic.wav"

- The Narrator

A towering and domineering force of seething rage and terrible intent, the Fanatic is a monk who has gone rogue from the church, hunting the Crimson Court anywhere he can find them. His scarred face reveals a past of consequential encounters with the malformed inhabitants of the Courtyard, having seen his fair share of the spilling of heathen blood. He has at his disposal several iconic vampire-hunting tools; stakes, garlic, and prayer. Nothing matters to him anymore except the pursuit of his righteous cause! Those he suspects tainted by the Crimson Curse, whether infected or sympathizers, will end up being burned at the stake. Countless innocent men and women have died at the hands of the Fanatic in his mad quest to cleanse the land of the blood curse. He will not stop until he is dead or has hunted down and slain the last vampire; at times, the line between zealous fervor and the wish for self-destruction are precariously blurred.

Behavior
The Fanatic is a boss added in The Crimson Court DLC. He is a wandering boss, like The Collector and Shambler, and he will hunt down your heroes, should they wander into a dungeon bearing the Crimson Curse. He will not appear in the game until a town event occurs declaring his arrival. Once he is in the game, he will randomly spawn somewhere inside the dungeon whenever you bring a party with Vampires in it.

If the game decides that the Fanatic is to appear during an expedition, a special loading screen with his face will show when the Dungeon is loading. This is your biggest warning that he is lurking somewhere within.

In particular, if you have 2 or 3 heroes infected, the chance of him appearing are 20% and 33% at medium and high infestation, respectively. If all four of your heroes are infected, there is a 75% chance at both medium and high infestation

Upon entering battle, the Fanatic will always surprise the party. If you decide to run away from the Fanatic, he will appear in the next encounter, fulfilling his promise to hunt "the Cursed" down. He will spawn in the two back ranks with his stake and pyre in the front rows.

During the first turn of the battle, he will perform "Sentence Rendered" on one of your heroes. This places them on the stake where they cannot do anything and take constant HP damage - every time any character takes a turn. The Fanatic has three turns per round.

While a character is burning the stake, he will use offensive attacks with 3 actions every round. His offensive attacks move him forwards and cause debuffs, while his buffs move him backwards away from the front line.

Unlike Hag's cauldron the pyre does not restore it's durability after the hero gets released from it. Fanatic will use as his first move in every round Fury of the Righteous dealing physical and stress damage to entire team in order to avenge his pyre.

Loot
Drops Crimson Curse-related trinkets, such as the Ancestor's Vintage and the Coven Signet. Subsequent Fanatic defeats will yield gem loot and other trinkets related to the Crimson Curse. Additionally, he can drop a special item known as "The Cure." Any hero who uses it will be immediately healed from The Crimson Curse. Like The Blood, all unused vials of The Cure will be stored upon returning to the Hamlet.

Strategy
The Fanatic is a relentless and challenging foe, and beating him with a poorly-geared party is nigh impossible. As such, he should be prepared for whenever you venture into a dungeon bearing the Crimson Curse. Attempting to retreat without abandoning the expedition is hopeless, as the Fanatic will simply appear in the next encounter.

Being able to move him across the battlefield or target all four ranks is essential to this fight. Like the Hag, the Fanatic will start every round using "Sentence Rendered" to place a hero on his pyre if one is not there already, dealing damage every action until they are on Death's Door. Whether or not you risk damaging the pyre to free the burning hero should depend on how much damage they can inflict - freeing the burning hero allows them to strike and costs the Fanatic an action, but striking the pyre buffs the Fanatic's damage, and destroying it altogether allows the Fanatic to use "Fury of the Righteous", which he will use every turn to deal devastating damage to the whole party. "Strike the Heretic" and "Holy Stake" are both high-damage single-target attacks, with the latter dealing extra damage to marked targets, so being able to guard and clear marks can go some way towards mitigating the damage taken.

DoT attacks - Bleed moreso than Blight - are highly effective (although at higher tiers, very unlikely to stick), since the Fanatic has both three actions per round and the ability to boost his own PROT. Accordingly, debuffs are extremely ineffective, as he will burn through 3 rounds of any debuff each turn. Ripostes can be useful, as the Fanatic's three actions and access to multi-party attacks mean he will likely trigger Risposte at least once each turn. As with the Hag fight, boosting the party's Dodge is also a viable strategy, giving you a chance to avoid "Sentence Rendered" and allow the entire party to deal damage. Stress is unlikely to be a significant factor during this fight, unless it occurs at the end of an expedition or during a Short quest where you cannot camp to deal with it.
