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 at the start of a run. Instead, she must be transformed into by holding all 4 Heresy items at once.

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

Along with these skills, the Heretic has extremely high base health, can triple jump, and has negative health regeneration, causing her to lose health over time instead of recovering it.

Tips

 * The Heretic's negative health regeneration is amplified by items such as the and . Without other items to offset the higher HP degeneration, these items can swiftly lead to her death.
 * Obtaining at least two will offset the negative health regeneration, and obtaining a third will allow the Heretic to heal normally again. This is only the case after avoiding damage for a sufficient period, which is easier with Shadowfade.
 * Since the Heretic's triple jumps are considered base jumps, each one is affected by, allowing for dramatic levels of air mobility.
 * Obtaining a at level 6 and above will also allow offset the negative regeneration, with even more extra healing the higher level the player is.
 * The Heretic's negative regeneration is not considered taking damage, and as such does not activate.
 * Activating a Shrine of Order can remove Heresy items. When this happens, the Heretic loses the skills corresponding to the missing Heresy items, and they are replaced with the non-functional Nevermore skill. If unlucky, this can result in her having no usable skills.
 * Selecting at the start of the game and transforming him into the Heretic will allow her to use  to destroy projectiles, as the Microbots are not lost when Captain transforms.
 * If the is enabled or the player has any, it is highly advised they do not become the Heretic. Her health degeneration is a flat amount, rather than a percentage of her health, unlike the healing from Shadowfade. As a result, lowering her maximum health too much makes her unable to outpace her degeneration with Shadowfade.
