When to use Cure 3 or not

[ManaKeKz]

did they change cure3 mp cost or have i missed something on Overcure that saves you mp o.O

Overcure: Grants a 15% chance that after casting Cure II, your next Cure III will cost half MP.

Cure III MP Cost @ 50 : 399

Overcure Cure 3 550 pot, 200 (199?) mp

I don't know of any changes to Cure 3, it has always been 399 mp afaik. I just can't remember if they translate the 50% reduction from Overcure (199.5) to 200 or 199 mp in the game. Or do they even work with decimals internally?
