This addon is as if you sprinkled minecraft potions on swords which will give the effect to you or your opponent depending on whether the effect is good or bad.

What this add-on does is avoid having to throw or drink positions in the middle of a battle, so if you need to drink a regeneration position, you just have to combine the desired sword with the position of the effect to be chosen in such a way that every time we hit a hit our opponent we will obtain the effect that we spray on the sword, as shown below:

In addition to being able to add the potions to the vanilla swords, the redstone and emerald swords have been added, let's start with the emerald sword:
