Hey RaiN!
The spells look awesome! But could you change 2 little things of them?
The bloodflurry spell, could you let him attack faster, so like 1 attack every 0.25 seconds because it might take a bit too long now. And with the Exile ability. Could you make it so that the knockback takes less time so it looks more powerful, and maybe add the special effect: Objects\Spawnmodels\Undead\ImpaleTargetDust\ImpaleTargetDust.mdl to him so it will look a bit more realistic.
But seriously the spells rock and you did them so fast
