Pain Absorption: Possibly lower the energy cost to 30, also make it so it transfers a condition into resistance. (For making it useful in 1 on 1 situations.)
Unyielding Anguish: Lower energy cost to 20, also add a 3 second CD to it.
Embrace The Darkness: Remove the energy cost, make the energy degeneration -5, not —7.. As for the fact it only increases all stats by 10%, also possibly raise the torment stacks to 2, not just 1.
