Im a 11th level cleric and 5th tier mythic. We just had a session where the whole party got shut down hard because the single enemy was stealthing and we just could not kill the thing.
How can we deal with something that is sniping us invisibly? Whenever we put up defenses to protect ourselves it stops attacking. It also seems able to teleport somehow, we suspect there is some kind of limit on that ability, but we dont know.
We already know that its not invisible as I had invisibility purge up and it filled the whole room. The room in question was dim light. Which we think had a large part to do with it as there are lots of things that dim light aids.
So what suggestions can you give for increasing our perception or negating the stealth when its not based on invisibility?
