Formulas

All results are floored (rounded down to nearest INT).

HP = VIT * 4.7 + LVL * 7.4
PATK = STR * 2.1 + LVL * 5.6 + 50
MATK = MAG * 2.1 + LVL * 5.6 + 50
PDEF = VIT * 1.1 + STR * 0.5 + LVL * 5.6 + 50
MDEF = VIT * 1.1 + MAG * 0.5 + LVL * 5.6 + 50

DAMAGE FORMULA = (ATK - DEF * 0.5) * 0.4 * (SKILL POWER * SKILL LEVEL / 100) * DAMAGE MODIFIERS * (1 * ATK BUFFS/DEBUFFS) / (1 * DEF BUFFS/DEBUFFS) 
10% variance in final damage. 
Critical hit multiplier is 1.5x

-Kaja/-Kunda effects (applied at end of formula) 
Rakukaja - 1 / 1.2 = 0.83x damage taken
Tarunda - 0.8 / 1 = 0.8x damage taken
Rakukaja + Tarunda - 0.8/1.2 = 0.67x damage taken
Tarukaja - 1.2/1 = 1.2x damage dealt
Rakunda - 1/0.8 =  1.25x damage dealt
Tarukaja + Rakunda - 1.2/0.8 = 1.5x damage dealt

STATUS CHANCE = BASE STATUS CHANCE + BRAND STATUS CHANCE + STATUS CHANCE PASSIVES - ENEMY STATUS RESIST + (USER LUCK - ENEMY LUCK) * 0.5
