not rolled by the roulette
Tornado is a spell skill that creates a tornado which repeatedly damages enemies around it. It will move forward for a duration, during which projectiles from you (or your skills used by proxies) can collide with it to deal damage as though it was an enemy. Then it will chase down enemies for a secondary duration, and reflect a portion of the damage it took from projectiles, in addition to its own spell damage.
