What is a bit frustrating however: 4 of the artifacts i found are light sources: ringil, frost treads, phial, arkenstone, ....
I like to play it, phasing through walls, playing a squirrel keeping the enemy behind a wall or rocks while talents recharge.
But: finishing level guardians to notice that the reward is contraproductive for a rogue is a bit annoying

Are there artefacts for thieves in the making?
