The OP can correct me if I'm mistaken, however I interpreted the RNG aspect of Shadow Form to be more of a bonus. Basically, it could work like Hallowed Ground (No damage whatsoever) or Holmgang (Reduced to 1HP).

As for the abilities themselves, I rather like everything you've proposed except Shadow Skin. It's essentially a second Rampart. Not a bad alternative per se, though my own thoughts were to overhaul the Dark Arts effect to be party wide mitigation. If I may borrow your format:

Dark Mind – Lvl.42 – Ability
Cast: Instant – Recast: 90s – Cost: 0 – Range: 0 – Radius: 0
Reduces damage taken by 15% for a duration of 10s.
Dark Arts Additional Effect: Reduces party damage by 10% for a duration of 10s

Increase the CD to compensate for the additional benefits while giving DRK an answer to Shake it Off and Passage of Arms.
