Armor trim buffs

I was thinking armor trims could have minor buffs. that wouldn’t effect things to much but would still be cool. Examples:

Lapis = more xp (only with full set equipped)

Gold = friendly piglins (only with full set equipped)

Emerald = better villager deals

Diamond = Very small protection boost

Netherite = very small knockback resistance boost + very small protection boost

Amethyst = level 1 regeneration (only with full set equipped)

Copper = attacks during thunder storms strike lightning on attacked entity (only with full set equipped)

Redstone = activate redstone dust by standing on it (boots only)

Quartz = after dying come back alive on half a heart

Iron = most basic mineral in Minecraft so I don’t think it needs a buff.
