Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Need help (replacing Lohse's special ability)

Would like to replace Lohse's "Maddening Song" with the elf racial "Flesh Sacrifice".

Is that possible? And, assuming things work like they did in DOS 1, any chance of a rough guide?
(what to extract, where to look for Lohse's abilities, the basics..)

My thanks for reading
