This mod is really simple and does exactly what is said in its summary. After throwing an Ender Pearl, if it hits another living entity like a mob or another player you swap places with each other instead of you just teleporting over to where the pearl landed.
By default the mod works only when directly hitting someone with the pearl. You can change the mode in configs to use a radius instead. Changing the value in the config sets the range a mob needs to be from the Ender Pearl meaning the pearl can also land right next to a mob and still cause the swap. You can increase or decrease this distance via the config file that comes with this mod. For example if you set the value at 10 throwing a pearl into the ground causes everyone in a 10x10x10 radius to be teleported to your previous location.
