I just had Energize played by an opponent, which "restores target's action point". What does that actually mean?
You remember that Gary told you each minion can only play one non-movement "action" per round and then becomes greyed out? Energize restores its ability to act and it turns colorful again.
When an NPC is part of a group, that specific NPC can only attack once, normally. So if there are five Kobolds in a group, all five can attack you, but just one time each. If only one of that five-Kobold group is in range of your character, they can still only attack that one time. Each individual Kobold has one action point to use; after they use it, their turn is over (other than possibly moving). Energize removes that restriction by restoring a used-up action point. Or, said another way, it gives them the option to act (e.g. attack) a second time after they've already acted once. Edit: Bah! Mightymushroom must have passed first last round; he was able to act before me.
