Food.

[Moth]

Ok I found it thank you! Is there any guide available that if I wanted to boost just mp gives me a list of all the boosts mp food etc.?

Pretty much all sweet foods will give you MP+ and mage-type effects such as magic potency and accuracy, etc. Anything sweet like chocolate, cakes, cookies, etc. All the foods fall under certain types of categories, for example fish dishes typically give only ranged+ stats, meat dishes give attack and HP and bread-type dishes give defense xD
