Yeah but the thing is, I die a lot so I'm thinking health, but I also wanna upgrade damage, and I also want steal.
Well, assuming a full Steal->Firestorm->Slowdown Build, you'll use 11/25 levels before your next upgrade.
Sacrifice would be another 1, and so would the upgrade. (But those are after you have a total of 25, so that won't be counted.)
You end up with the choice of 14 points you can allocate into 4 skills, which are HP, Stats, SP, and ATT.
SP Seems one of the most useful, then whatever your preference is, but ATT seems the least useful as stats adds both ATT, DEF, and Crit.
