I am Trying to make it shoot arrows at the palyer as an ability

This mod is for 1.9.2 and is working fine except for that it is a reaper mod with a new mob the reaper it is a boss the can explode and is spoused to shoot a barrage of arrows at the player it shoots the arrows just in 1 direction and it shoots that direction every time it shoots. This is not in ai it uses a world tick update trigger. I am using the projectiles section in the trigger with the shoot and then the arrow details copy pasted with a 35 tick delay and 1/500 chance

. If you can help it would be greatly appreciated.
