Xulu Client Mod 1.12.2 is a free and open-source PvP client aimed at the anarchy movement. This client can be customized to serve as a secondary client but is not used often as a primary client because it lacks modules for pvp. The default clickgui button Y is used. If that fails, do.bind clickgui.y to make it work. Fastfall is a module that automatically causes you to fall at terminal velocity. However, this can sometimes lead to issues with reverse step.
