At the moment, you can only tell a player to drop a Grimoire they’re holding if opening the social wheel while looking at them. I think there should be more interactions - primarily, I’m thinking of certain boon/item combinations in Chaos Wastes, or those using Natural Bond.
Add options to ask another player to give you a Healing Draught (or heal you with a medkit if they’re holding one), their potion, or a bomb (in the case of OE with multiple bomb types, allowing choosing specific bomb type).
