This macro is designed for the effective use of anchors in the Minecraft game. To use it correctly, you need to place the anchor in the 4th slot of your inventory, and the lightstone in the 5th slot. After activating this macro, by pressing the appropriate key, you will be able to automatically place and detonate 3 anchors at the same time. This is originally intended to help in PvP battles, where such tactics can be extremely useful.
