I've been playing Murkon's Refuge on level 4 for over a day now, and still can't get past that bloody Gatekeeper.

I have one Wizard of level 11 and one Sorcerer of level 11. I suppose they could keep on casting attack spells to kill the Gatekeeper and his henchmen, but all the monsters along the way use up my spell points.

Can I cast Conceal in advance at the door before the Gatekeepr? Or will it only work in battle?

I've found out that an easy way to gain experience and money is to go to level 2, walk to the door to the really big hall, then walk to the opposite wall and back again, killing every monster along the way. I typically have to do it once to be able to resurrect one character, and when I have more characters alive resurrecting the rest is even easier.
