Here are some some spells I'd like as a BLU. I want some for the damage, some for the effect, and some for the animation.

-Spike Flail Massive damage. Dragons.

-Hellish Crescendo: Area of Effect damage with Additional Effect: Paralysis. Great animation and effect. Caturae.

-Hellsnap AoE Stun. Great animation. Dvergr.

-Cyclonic Turmoil: AoE Wind damage, Knockback, and multiple effect Dispel. Great effect. Pixies.

Leeching Current: AoE Water damage + HP drain. Great effect.
