A couple more:
-Flame Breath and Blaze Wall remove status ailments
-reason: they try to add a dummied state 02 (probably burn) and new state overwrites old state
-Heal Light and Tinkle Rain "heal" maxHP up/down (specifically the flags); the effect is visible on the next HP update
-Transshape lasts shorter the hgher the target's luck is (25-luck, min 1, to be precise)
-when transshape ends, it also clears maxHP modifications
-Contrary to rumors, stats have no influence on casttimes; only class rank does, with each class change being 0.5s faster than before. A cheated 3rd class change would make the casttime be dependant on your saber element though.
-If you have 20+ luck, your luck gets maxed the next time you receive exp.
less bug and more strange feature:
-if monster have two affinities for one element, the weaker one gets removed; e.g. reflect&drain fire becomes only reflect fire (annoying as only spells get affected by reflect)
-Counter Magic doesn't work on elements that you have any affinity (good or bad) for, only neutral becomes reflect
--or rather Counter Magic doesn't work, period
No bugs, but wasted effort:
-equipment can grant auto-buffs, e.g. start battle with power up effect
-equipment can grant bonus to luck for a not used value
-there's an unused status buff that makes spells cost half MP (01 where you'd put maxHP buffs)
-there's an unused status buff that makes spells cost double MP (02 where you'd put maxHP buffs)
