Tiny mod that tries to eliminate those kind of situations when "I wanted to hit the mob, not the grass". Now you can hit mobs behind the grass!
This works on every block that have no collision box (i.e. you can walk through it) not only vanilla but also modded ones, e.g. grass, flowers, saplings and even cobweb.
Must-have for modpacks that rely on combat mechanics.
Vanilla clients can connect to servers with this mod installed.
