This is a clientside mod for the newest snapshots currently, taking advantage of attribute swapping tech in order to perform a DASH/ROLL upon a keybind press of your choice, entirely in vanilla Minecraft . Essentially, as long as you have a Spear enchanted with Lunge in your hotbar, you can perform a dash in ANY cardinal direction, including backwards!
Exclusive feature to the premium version:
If a spear without lunge is in your inventory, and you attack a mob that you normally would not be able to reach with your held weapon, a spear swap is attempted to bridge the gap. Clientsidedly this feels like higher range, which it practically is.
