Did I heal during the short rest after the goblin fight? If not, I'm gonna invoke my last lucky point and make the barbarian reroll that attack. 7 takes me out to -1. ^^"
Yeah, chances are Pylia would've patched you up or fed you a good berry. Pretty sure you only took 3 damage, so one good berry will bring you back to max. That being said, you can still invoke the last lucky point if you want.
Your object interaction is a type of nonaction, such as opening a door or drawing your sword. Unless you had intended to take out multiple Items you still have a regular action to take.
