Curios-equipped jetpacks can provide their base chestplate armor stats.

Available options:

Enable or disable Curios jetpack armor stats.
Choose whether armor stats only apply when the normal chest armor slot is empty.
Or allow Curios jetpack armor stats to stack with normal chest armor.

This feature applies base armor attributes only (armor, armor toughness, and knockback resistance), enchantments or modded armor hooks will not behave like they do in the normal chest armor slot.

Works in LAN/multiplayer when installed on both server/host and clients.
