DRK got it's uses. When i'm tired and sleepy i can just pick it up and mindlessly spam 1-2-3 with ocasional edge of darkness or unleash + flood of darkness. With how slow that class is even sleeping mind can handle it. I wish they gave you blood skills at 30 and darkness at 60. That 10% buff at low lv is crap anyways i'd rather have 2 more skills early. Unleash should also generate blood so you can spam Quaietus earlier than lv 72.
