Ok so i have a limited number of spells per day (depending the spell). I just didn't get it on the messy UI / Lack of tutorial. Thanks for answers
There's a set of boxes that have little blue boxes in them, just above your toolbar. They have between 1 and 4 blue boxes in them: Those are the spell slots that you have at your disposal. The "empty" blue box is for cantrips; you got infinite those. Mousing over a spell will let you know what level it is by default, and most can be upcasted at a benefit (when attempting to cast, it will give you a description of what you get for upcasting, if anything). Can't upcast cantrips.
