Knockback nemos drop rarely from emerald ores, which is exactly the problem. In a game, that one person that has a nemo will destroy anyone and everyone (probably) as long as the other person was near the void. So, I suggest to make them a 5-time use only since a one-time use is a bit harsh considering the rarity.
More information: Display the durability bar to show the player (that has the nemo) how many times it was used.
Seems pretty balanced to me. I suck so much at skywars. I’ve played 780 games and i’ve only won 88 of them, and i keep dying to the stupidest things. This would help just a little. Voted!
I actually think this could be a pretty balanced idea. Maybe make the durability something like 20, because if you know how, it can be easy to counter Nemos, but in conclusion, cool idea.
