The game causes lag by opening inventory with items, trying to trade with villagers and opening chests
and the lag intensifies if you have full shulkerboxes in the inventory

The critical attack effect is below the mob (at the feet of the mob)

increase the spawn of the mobs since the games is very easy in hard difficult and because the shields cover any attack

affects the 1.10 and the 1.11 (beta) in both android and in the W10E I have a low spec pc

there are no more performance problems
