Astrub Tunnels

The Astrub Underground is at the Mine (6, -19) with the Sickmildewstering Rats. It's where most first missions like the Xelors and the Efaclips end. Most Sickmildewstering Rats are lvl 10 or 13; the lvl 13 tend to have Tofu (lvl 2 to 4 usually) with them. Not really meant for low level players as they can attack twice in one turn casting punch. There is a mission in there as well which ends by killing a lvl 30 Sickmildewstering Rat. If you really want to fight it do it with higher level people; if you are already a high enough level you can tackle it for some decent experience.
