Lol, was messing around with Temple Leves the other day and was doing one of the escort ones (you know, with the /beckon command), and a FATE spawned right on top of me with about 8 mobs out of nowhere. They immediately rushed me and started attacking my escort NPC. Was able to fight them off as a Summoner with my choco and egi out, but it was a brutal fight that would've easily wasted my 10 leves if I hadn't been quick to react and run a bit.
