while this might have changed - i know @ one time charms gave your bots 0 stats and basically just ate them, so not really worth your time/effort i think. now this could have changed but dont remember seeing a change on it lol.
Nah, bot doesn't eat it, they actually equip it in the charm slot like you do. I always get one for each bot, and if you need the charm back for whatever reason, #bot inventory remove Will give it back to you just like any other item.
