my companion is the healer found in the bar (forgot the name). The first time we fought she did a heal but since then whether fighting or by me asking she does not heal me. Give me that "... sorry" message and that is that. Luckily she fights and heals herslef so now my priest is the tank and I fight with range stuff from a distance but that obviously cant last the whole game.
Also on a seperate topic can the stuff you loot get used by the comapnion? I am a monk character so I see no need to save spells I loot or stuff used for potions since I cant do those sorts of things. Hate to sell them only to find out I could share the stuff.
