golden tools are meant to do +2 extra damage i tested this and it doesnt work

that is literally impossible, do you have the origin selected

Here's an image for reference, the last stats refer to health before / after a full hit with a gold sword (which does 4 dmg by default)

I correct myself the last two are for a golden axe, which does 7 dmg by default

check again, just because it doesn't appear in the tooltip doesn't mean it does not apply

i tested it i compared it with a iron sword and iron sword killed zombie in 3 hits while golden sword killed the zombie in 4 hits
