Go!
Money, weapons, gear, magical items, every valuable thing you can imagine is in the dungeon. All you have to do is explore to your heart's content and conquer it with all your might. I'll take care of everything else for you.
Not enough supplies? I'll restock them.
The maze too confusing? I'll map out a route.
The enemies too strong? I'll find their weaknesses.
What? A price? There's no price. I don't want your spoils, and I don't need your lives. You can take everything you manage to carry out of the dungeon after conquering it. But any part of the dungeon you can't take with you will belong to me.
