So, here's the situation: the druid in my party is a genasi who is looking for her brother, who vanished looking for their genasi tribe a year ago. I've decided that the enchanted forest to the northeast of the city is where he is, along with all the other genasi who have been lured there. I'm thinking the culprit is a hag who is harvesting the genasi's elemental essence for...something. Not sure yet.
However, I don't want this to be a straight up combat encounter. At this point in time the party doesn't know to suspect a hag, but hags are supposed to be tricky, right? They don't fight unless they need to and they always have a backup plan. I'm trying to figure out how to play this hag intelligently so they don't go in guns blazing and steamroll her.
This idea is still very new in its concept, so I'm sorry I don't have more details yet, but if anyone's run a had encounter or an encounter with a similarly tricky opponent, do you have any advice?
