Heretic

Kur-skan, the Heretic is a secret playable character in Risk of Rain 2.

The Heretic cannot be selected from the character selection screen and must be transformed into by collecting all 4 Heresy items in a single run.

The items in the set and their respective skills are:
 * - Hungering Gaze
 * - Slicing Maelstrom
 * - Shadowfade
 * - Ruin

Along with the skills, the character has high health, loses health over time, and has a triple jump. The health loss over time is caused by negative regen, which will be sped up by regen multipliers like. This will speed up the health degen and can kill you much faster over time. Although this can be negated by using which will remove your negative health regen and stop it from killing you, at the cost of turning your health into shields.

Tips

 * Obtaining at least two will allow you to negate the negative health regen penalty (as long as you don't take damage), and obtaining a third will allow you to heal normally again.
 * Since The Heretic's triple jumps are considered base jumps, each one is affected by, which allows for dramatic levels of air mobility.
 * Obtaining Gnarled Woodsprite at level 6 and above will also allow you to negate the negative regeneration, with more healing the higher level you are.
 * The negative health regen does not activate Razorwire.
 * Taking a Shrine of Order can remove Heresy Items. When this happens, any Heresy items you lost will cause you to lose the skill, as they will be replaced with a non functioning skill. This can result in you having no innate ability to attack.
 * Selecting Captain at the start of the game will allow you to use Defensive Microbots letting The Heretic destroy projectiles.

Trivia

 * The Heretic has the highest base health, and base damage of any playable character, at 440 and 18 respectively, they also have a base speed of 8 m/s, which is 1 m/s faster than every other playable character.
 * has several unique interactions during his fight:
 * At the beginning of the 4th phase while absorbing items, the boss will not take the items related to your transformation and you will not revert to your previous Survivor.
 * He has unique dialogue, telling the Heretic to "die again". There is also unique dialogue for when the Heretic has the ; "THE HERETIC… THE GUARDIAN… HOW? WHO PULLS YOUR STRINGS, VERMIN?"
 * If he kills the Heretic, Mithrix will say, "Return to pieces heretic", Referring to the evisceration of the Heretic in which their eyes (Visions of Heresy) arms (Hooks of Heresy) legs (Strides of Heresy) and heart (Essence of Heresy) were each to be scattered across "the farthest depths of the Moon."
 * Without any heresy items the Heretic has no useful skills, only one skill called Nevermore, which does nothing but produce an audible squawk, with a 1 second cool down. This is a reference to the poem called The Raven by Edgar Allan Poe.
 * The Heretic's negative regen will be reduced or amplified depending on the difficulty, with reducing the health degenerated per tick and  amplifying the health degeneration.
 * The ending phrases for the Heretic seem to be referencing the fact that they are actually two distinct beings: Kur-skan the Heretic, and the survivor you were playing as that is currently inhabiting her body.
 * The Heretic seems to be a deformed Alloy Vulture.
