Devestating Critical - +1d10 on crits as a daggermaster it's very nice too
Blood Thirst - +2 damage to bloodied foes, stacks wtih merciless killer.

that's 18 there, I'm sure I'll want others too but I think that may be my set of 18 by 30.

Whirlwind sneak attack looks kinda sexy too, combined with Martial mastery if you move first run up, aoe blast sneak attack a group, action point and do it again with the same power. sneak attacking everyone twice in one turn. and if you crit on anyone during all this, regain hte use of the encounter power you used to do it wtih again.
