Nah I'm fine with the sword only

Oooohhh neaaaat
May you add some unbreaking enchantment
But yeh fire aspect goes lit
And getting a trident?
So you can enchant it with water propulsion and fly while it's raining?

I'd use XP in leveling abilities and
The strongest or most effective will have the most points,
The best defense is offense ,
I'd use Xp in enchanting my netherite sword
With sharpness
Knock back
And fire aspect

Niceee
And what will u do with the XP? Leveling up?

Well of course yes
