4. Place prismatic crystal
(5). If the previous fireball didn't crit, keep casting fireball until HU procs.
6. Cast a last fireball while you have HS+HU
7. Spam pyros until you run out. (1 is minimum, 3 is maximum)
8. Cast combustion. (After last pyroblast landed)
9. If you're running living bomb, apply living bomb and then spread dots with inferno blast. If you're running blast wave, spread combustion and then use 2 charges of blast wave.
