The Dual Combo Assassin
I find that this is a great pressure build, if not an all out spike. The first is pressure, applied by the Jagged+Wild+Critical Combo. Now, heres the nice part, the recharge times on both leads are 4 seconds. This enables a Jagged+Wild+Fangs Combo to reduce the targets health by near 50% or if he is near 45-50% it will most likely kill them. I origionaly had Seeping Wound and Shadow of Haste, but I found that the damage does not suffer much from the lack of Seeping Wound. So, I added Aura of Displacement, the de facto skill for assassins. I added Critical Eye to increase the energy regen even more to make critical strike cost 0 energy after it hits. I would like to note that this build also nets 5 energy per critical strike, making a usable pressure build as well.
