Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Tenebrium - what, where, and how?

one rank in Tenebrium is enough to handle Tenebrium weapons; the skill is to "handle/use" T weapons, not cure rot.

currently you can cure everyone with a bloodstone, you're going to use some to finish the game anyway.

afterwards, the character with T skill can handle T weapons without rot. if you want everyone to use it, finish the Troll's Bounty "side quest." that quest can be done with stealth; but if you can actually find your way into the cave, fighting those trolls shouldn't be a problem...

lastly, there'll be a main quest for which one of your main characters need to use T weapons...
