For those who want to make melee and projectiles manually dodgeable.

If you want to make a more action oriented boss you might want to make there basic melee attack or projectile dodgeable.
It's very easy...
Set the attack type for dodging projectiles either choose artillery or artillery line. depending on whether you want his attacks to shotputs "ones you can run in any direction to dodge" or artillery line "ones you have to dodge either left or right or get out of the range"
average projectile speed is about 800, the higher the speed the harder to dodge... For melee attacks, use artillery line and have the projectile spell about 300, but use no projectile graphic.
that way it looks like his attacking normally, but if you move to the side fast enough or back out of his melee range, you can dodge the attack, again higher projectile speed is harder to dod
