I created a new design unit using the ice staff (whatever it's called) and for some reason it doesn't have an projectile animation. You see the units wave their staffs and then nothing for a good 10~20 seconds (depending on distance) before the enemy takes damage. It's an absurdly long time compared to all the other attack animation, and there's no projectile at all!
The unit i designed had the ice staff, a horse, an ice ring and 3 traits.
