your pics are showing up from here. Glad you scaled them down too.
Frost fall, I should have added in, has a chance to miss. If a share doesnt hit a target, it wont take damage. Kind of random actually, sometimes every cast will kill a whole spawn, sometimes it will miss 3/4ths the spawn. Not the most predictable skill, but it really is quite strong in bigger games especially. Like a lower mana, better CD barrage, with a chance to miss. Never seen it miss a hero though.
