adding a frost spell category as a new element, idea for what the spell could do:
-Icycle (just a small percing projectile that does a lot of damage)
-Freezing feet (would let you freeze your own feet and make you slide, faster than walking also)
-Freeze ray (laser that freeze enemy)
-Self freeze (turn yourself into a block of ice that gives you 70-90% damage resistence but you can't move or shoot)
-Blizzard (freeze enemy in a big area with damage over time)
