1. Okay so I learned I need tenebrium weapons to affect these void demons from the imp fellow , However I do not have the skill , Did I miss something ? as I'm honestly not sure where I acquire this skill
2. the Goblin Mines , So there's a spell that will make these Death Knights killable , is it learned inside the mines or some where else? as I lack any sneaking so I doubt I can just sneak by them.
You can get the skill to use Tenebrium weapons by solving Brandon's quest in Silverglen.
You cannot kill the Death Knights in the mine. You have to sneak in the mines (or use invisibility).
