@the other guy: Curing would work the same. Heal over time for a set amount, or heal in chunks with recharge rate (same as rate of fire).
What I'm trying to imply is magic being used for other things than what you've mentioned or can be scaled with numbers. How about Water-breathing, Invisibility, Chameleon, Detect Life, Levitation (big if), Summonings, Bound Equipments, etc.
