This trick is good for undead things like zombies, skeletons, wither skeletons, husks, strays, and Withers. SmiteV counts as instant death on most undead mobs.
Creepers and endermen are kinda annoying to get rid of, I recommend doing critical hits (see M-craft Pro. PvP tips for more on critical hits) to get rid of them, and just remember, creeper explosions go all to armor so have that at hand when you can.
Some enchantments are very powerful and useful when fighting mobs and heck, pretty much everything. A example of a good book setup.
I know this doesn’t look like much but this is confirmed one of or the best ways to set up your Enchanting table.
