Idea 2 Ideas.

1. Is that not already a feature of Minecraft? Or has it been disabled in some way...

2. Sounds like a good idea, it could cause people to keep on enchanting, then they know they have a bad enchant so re-enchant. Yes, I understand enchanting costs Lapis and Experience, but there needs to be more of a penalty so players aren't encouraged to keep on doing this. Considering Enchanting how it is, is already pretty OP. So, I don't know, costs 1 gold to unenchant? Just any type of penalty.

 

I've watched a Blaze grinding video, and he threw a potion and help the sword right after he threw it and got a bunch of XP... I'm not really sure about that. But I'd wait for the confirmation of someone who really knows their minecraft :V.

 

The looting enchantment has the following effects: Mobs can drop more loot increases maximum loot drop by +1 per level. Increases chance of rare drops by +0.5% per level (i.e., 3% at level I, 3.5% at level II, and 4% at level III). Looting however does not give increased xp.

 

1. As lozzy said above me, looting does not give xp, but I like the idea. But how much more xp should you get? Maybe:
Looting 1 x0.5?
Looting 2 X1,0?
Looting 3 x 2.0?
(Only spontanian ideas)

2. I don't really like this idea, then if you get a crappy inchantment, you could just remove and then go again..
However if you got between 50%-75% back based on the level which it whas enchanted with? Then it's ok I guess.

Sorry if there is any grammar errors, I typed this on my phone.

Very many people complain about enchanting being too OP, and there being too much prot 4. Would this not add to that issue? I think this would be cool on say a factions server, but I think it would be too OP here and would ruin the Vanilla feel.

 

That's a trick where mobs are killed by an instant damage potion - on their death it basically checks the players hand and if there is.a looting sword it applies the looting effect to the mob drops - fast way of killing a tonne of mobs with looting effect.
