Your Most Favorite or Original Spell Effect.

[Ranorak]

We've all seen the fireball by now.
A orb of fire moving forward ending in an explosion. Iconic as it may be, it's just nothing new any more.

So what is your favourite spell or attack animation/Effect in a video game?

For me, it's the lightning whip from either Dragon's Dogma or Guild Wars 2.
