Charotte's status:
STR = 5 + 0.7 * Lv
CON = 3 + 0.6 * Lv
INT = 8 + 1.0 * Lv
MNT = 8 * 1.2 * Lv
LCK = 3 + 0.5 * Lv
Dart's original damage (seems to be the
accurate formula):
initial damage = x - 5
and
extra damage = x * 2
where x = [([INT/8] + [INT/32] + 7) * (1 + SP/200)].
Astarte has 1500HP, 0DEF, and is susceptible to slash-typed attacks (all such damage * 1.25) e.g. Dart. Go figure.
Note: Lv = level, SP = skill points,
[something] means to truncate
something into an interger
EDIT: I don't know why, but STR boosted with spells is much less effective than (about half as) that with equipments or level-ups, while INT boosted with spells is just as effective.
EDIT 2: Birthday cakes? Don't we already have infinite potions thanks to that item glitch?
