This mod adds the "/lag" command that gives an effect, that after 5 seconds or after the effect expires, it summons so much dropped items and so much particles it will crash your game before the particles and dropped items could be seen by the player.
WarningThis mod is better alone rather than in a modpack. But do as you wish with my mod in your modpacks.
