The extra bullet damage will work like bebop hook 1 AP upgrade, so it multiplies the FULL damage that the bullet would have done(alch fire works this way i think).
The direction change will need a MIN and MAX angle that it can bend the projectile path. Basically make enemies miss their spells(will work for bebop hook) and shots, but in a fun way . Don`t know how powerfull this will be, might need higher CD.
Also somewhat inspired by paradox wall.
