MC-131637The slowness effect is applied to entities when the bane of arthropods enchantment is held in the off hand
The Bug:
The slowness effect is applied to entities when the bane of arthropods enchantment is held in the off hand.
For example, when you melee attack a spider while having an item enchanted with bane of arthropods in your off hand, the slowness effect is applied to the entity you attacked. This doesn't make sense because the off hand item isn't being used.
Steps to Reproduce:
- Hold a sword enchanted with bane of arthropods in your off hand by using the command provided below.
/item replace entity @s weapon.offhand with minecraft:netherite_sword[minecraft:enchantments={levels:{'minecraft:bane_of_arthropods':5}}] - Summon a spider and attack it using your main hand.
Observed Behavior:
The slowness effect is applied to entities when the bane of arthropods enchantment is held in the off hand.
Expected Behavior:
The slowness effect would only be applied to entities if the weapon used for the attack has the bane of arthropods enchantment.

Bane of Arthropods in off-hand effects attack
When you have an item that is enchanted with Bane of Arthropods in you off-hand and damage a spider with your main-hand weapon, Bane of Arthropod is applied to the spider.
Expected: Bane of Arthropods should only apply when it is on the weapon that is used to attack.

The same applies to Thorns. Holding an item with Thorns on it in any hand damages the attacker.
Same root cause, just a neighboring method (Enchantment.onEntityDamaged() vs Enchantment.onUserHurt()).
Confirmed for 1.13.1-pre1

A side effect of this is that it apples the enchantments for "main hand, off hand, head, chest, legs, feet, main hand". Notice how "main hand" is doubled up here...
Not 100% sure if this duplicates MC-3304. If not, then it definitely relates to it.
The slowness effect from the enchantment is only activated when holding an item with bane of anthropods in the offhand. However, it doesn't amplify damage under these circumstances.
