We're doing Evil RP pvp --- in groups --- so he's tactic is going to be an assassin with high burst dmg. If they do get to hit him (meaning they don't die immediately), he's going to run and hide and heal with Cu Sidhe passive healing.
... you'll want 100 Str then for the "100 Str bonus."
Other than that, you'll have to test it out yourself and see what works, If you want to chain a bunch of specials, you'll need a high mana pool.
Perhaps fencing with a high SSI kryss and warfork would work well.
...then again 35 damage AIs might be a bit weak for what you're thinking of, but the LP and bleed and AI combos will probably get them running anyway.
Is that a support assassin, or a solo? If you pair up with someone, they can do the bleed/mortal/disarm/whatever and you finish with LP and AIs.
Consider pairing yourself with a necromancer so they can corpse skin which increases poison and fire damage by 50% against someone who hasnt overstacked their resists.
