Did not post for a while, but I see
* If a character with very low MaxHP loses Vitality due to a Brand, their MaxHP may reach 0 causing a crash/hang.
Was found and fixed.
I'd like to note that the ri-family of cost reducing brands would appear to be too strong.
Stuff like:
Soul Brand:
Ri-Cl-Tra (Lv.30)
HP equal to MaxHP
Agility: -19
SP Costs: -93%
Ri-Ef-Fr-Tir (Lv.9)
SP equal to or less than 50
Vitality: -9
SP per Turn: +2.4
SP Costs: -28%
Ri-Ef-We-Tir-Ab (Lv.15)
No Body abilities
SP equal to or less than 50
Strength: -12
SP per Turn: +3.6
SP Costs: -45%
Are all absurdly strong, and generally obtainable at a reasonable level.
Also, strength runes probably need higher numbers than other stats, because otherwise, due to the lack of high-sp cost physicals, they aren't very potent(until powers show up, which feel like a mini-perseus in packs)
Edit:
These were all different runs that ended up on floor 20+
