If you'd like to reach insane damage I recommend a human, and here's an easy strat for them:
Prep JJ and reach at least 70 HP/ 27 MP at level 1. You'll need the Fire Heart, LEMMISI, B2P, HALPME and a max mana item to convert...
On long cycles you'll need to cast 34, on short ones 33 glyphs. I made an excel table to show what to do to make it work.
Always cast the glyphs first, and FH later. I indicated with green when to activate it.

When you forget where you are in the cycle just look at your CP and divide it by 3. You can find your table from the remainder value, then find which step you are on by the "normal value".
When casting always keep in mind what is the CP where you need to stop. On most parts it's unnecessary cause you'll see that you can't cast more B2P or HM without wasting anything.
If you screw up something you can corrigate with B2P and FH. While long cycles cost 2 HP, the 2 short ones generate 6 surplus each if you cleverly use FH.
But to make it foolproof you could request a 4th health boost from JJ and your margin of error would skyrocket.
Have fun with it
