How would you do tossing an item to a companion.
There are already rules for throwing and object but I'm not sure about catching.
I would do a dex check and make the difficulty 10.
Perhaps higher if the item was sharp, fragile, oddly shaped, or large. I am not sure that RAW exist to deal with this.
