Tornado

Key details

• The way to use Tornado is to lay down many them.
• The spell creates one medium-sized (size 3) projectile that moves in a non-random but erratic trajectory away from the caster for 3 seconds.
• Tornado's projectile actually deals two different sets of damage, which can be described as "collision"damage and "periodic" damage.
• Collision damage can be blocked with a shield, but periodic damage cannot.
• Any target that comes into contact with the projectile itself will take collision damage.
• Collision damage is subject to a 25 frame Next Hit Delay and utilizes the Last Collide mechanic, making any given target extremely unlikely to be damaged twice by the collision damage from a single casting of Tornado.
• Every 15 frames, Tornado will deal periodic damage to any target within or adjacent to the projectile.
• Periodic damage is subject to neither Next Hit Delay nor Last Collide.
• It is best to aim past a monster sort of like Barbarian's Whirlwind rather than click on a monster and cast.
• Once you have experience with Tornado you can use it more effectively.
