Thank you for replying!
It's actually only those 2 mods that pushed me towards the Defiler. Not getting a penalty for dying (I've only played the game for 3 days and only found out today, that putting skill points into the mastery bar increased my HP, so I've been dying a lot, lol) and mainly being able to enchant(?) items above the green rarity. I discovered earlier that that's apparently not possible, which makes all of the charms I've farmed for completely useless, now that I'm finally decked out in blue. My brother - who has been an avid Titan Quest-player since shortly after it was released - has tried to help, but was also unable to find a workaround. :/
