I know that to be able to cast spells as a ranger you need your wisdom to be 10+level of spell. But like, is that wisdom base or modified? So say can you roll a ranger with 10 wisdom, wear +4 wisdom item. Then will you be able to cast a level 4 spell? or to cast a level 4 spell, you have to roll with 14 wisdom at beginning.

-early thanks for response in advance
