I looked into necro a couple of times but there are something missing from it so i created a couple of skills for necro which I think would make it better.
Spectral Traversal – Teleport. It needs mobility, has almost none atm only ground target teleport is through flesh wurm.
Plague Flare – Corrupt ground, the corrupted area removes conditions from allies for 5 seconds or until it removes 5 unique conditions. After it expires it explodes and inflicts stored conditions to nearby foes and knocks them back – blast finisher.
Sanctuary of Death – create sanctuary of death that heals allies and removes conditions form them – if foes get feared away and get 1 random conditions – unblockable.
