Simple Health bar addon
With the Simple Health bar addon, every change in the mob's health pool will be visible. No matter whether hostile or peaceful, every mob will be assigned a health bar above his head. With such an indicator, they cannot sneak around you being unnoticed. Now you will know exactly how many hits it is left to beat a mob. It's a simple mod, but it's his strength, and it works nicely on servers too.
