📍 Description (REQUIRED)

The Talisman of the Anvil and the Ender version do not prevent 1 armor piece from breaking if it is on any armor slot and your main hand is empty.
The normal and the Ender version do work if:
-You have in your main hand any item (sand, gunpowder, a pickaxe, the sf guide, etc).

I found this bug a long time ago, it happened on every server I played.

📑 Steps to reproduce the Issue (REQUIRED)

1. Get some Talismans of the Anvil (normal or ender) and put them in your inventory/enderchest.
2. Equip any armor.
3. Leave your main hand empty to see the bug.
4. Break the armor by any way (TNT, fire, lava, etc).
5. See how the message ("Your Talisman saved your tool from breaking") appears, the talisman is consumed but the piece of armor is gone.

I did a quick video demonstration:

💡 Expected behavior (REQUIRED)

I expected that the talisman would work on items with durability (mainly armors) on the armor slots without need for an item in the main hand.

📜 Server Log

This error appears in the console when the talisman attempts to prevent 1 armor piece from breaking with the main hand empty:

There are no errors if you have any item in the main hand when the talisman does the magic.
