Skill point pool

Whenever a character gains a level, she also gains skill points as indicated by her class, background, feats, and int modifier. These skill points can be expended to improve skills as usual, but may also be stored in a skill point pool, to be later applied towards learning spells. Learning spells requires either study and practise, which involves investing at least 1 skill point per spell level, which puts the spell into the character's spell pool, or active casting, meaning the character needs to make a successful casting check to cast an unpractised spell at the usual penalty. Failure to successfully cast the spell leads to a miscast, which may have negative repercussions.
