Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Killed fire elemental lord Sua

Hunting for the white witch in Hiberheim when I free the elemental lords and kill them all for some bonus XP/loot.

Now when I try to summon Sua to free the white witch all I get is a message saying "Nothing... I suppose the Lord of Flame has better things to do than heed my call."

How do I free her if I killed Sua?
