Basically start off either defensive or offensive based on what you're attacking, and mix 'n match as needed:
prep: crit eye
defensive: siphone strength + crit defenses, these with crit eye will keep you defenses going for ages, especially since your dagger damage is fairly basic, with 13 crits you will get the energy back quickly to go on the ...
offensive: lay down the coals and knock them into it with tehnai's wind, when the get back up, hit them with dancing daggers and then knock them back down again with entangling asp, which poisons them for ages as well
I took the two different lines of attacks to handle poor cooldowns on the pyromaniac side, and basically by switching between coals and poison I can keep going for ages with defenses up. It passed the jade knights test and it's great fun watching them alternatively turn green or run around on fire

Anyway, just for fun, maybe someone can make it better, here's hoping
