Arcane Ice

You perform a ritual that causes you build up enough arcane energy to make a Sturdy magical Ice that cant be broken by anything nonmagical. The spell uses a 10 hp when cast and either heals an ally you touch for 10hp or damages for 10hp on touch (frost damage). You can make another type of attack by impaling an enemy with different sizes of spikes. One large spike (2d12), three medium spikes (2d10) or 5 small spikes (3d4 3 times)(for this certain choice of attack you need to roll 3 times). Also, your Ice makes a five-foot-tall trail from you to where you cast acting as a wall.
