NHF – new heroes for Heroes V 3.1.

Surprised me. Chaos is the foundation for a Warlock. That's how the developers intended it.

However, he immediately has this skill, and even though Warlocks are conceived as eternal users of Chaos, this character immediately sets a framework for how the game will be played with him.
P.S. Personally, I would really like to see a "fallen knight" character in the regular version, because this special ability is quite rare, and I would like to try playing with a character who has it.
