Different Aim Assist hacks.
Bow Assist
Once you start using bow, module searches for the closest to your crosshair living entity, and if it is possible to reach it with arrow and current bow power, then module sets its target as current entity. If you release bow you will rotate to the proper rotation on the server and shoot the arrow.

You can add below script to Status Overlay module to see what is current targeted entity: Or you can configure Entity ESP to highlight this entity via custom script. Add Entity ESP entry for LivingEntity class, check "Enabled", uncheck "Tracer", check "Outline", uncheck "Collision Box", check "Custom Script", add below script, click "Save" to save the script, go back to Entity ESP list, and move LivingEntity to the top on the list:
Target Lock
Allows you to lock your crosshair to specific entity and follow its movement. Use Event Scripting module to automate enable/disable locking. Example:
Target Center
Target Top
