A very strong dagger

Harnessing the energy in the stone from the archer demon as well as two of the others you get the idea that three is a powerful number. Setting the dagger in the triangle you perform the ritual. The whole area glows with ever increasing energy till finally there is a whoosh sound and everything vanishes, except of course the newly enchanted dagger. Outwardly you can tell it is yet sort of isn't the same, it now has a double sided blade, as before but a tad longer possibly, tapering to a point more gracefully and evenly than before. Picking it up you find it lighter and better balanced as well. You can't resist and throw it across the room at the wall. With a heavy thud it imbeds itself into the wall. An instant later it is in your hand. “Sweet.” Standing you walk along and drop it, sure enough it teleports itself back. “Really sweet.”

Next you gather up what little you have when an idea forms, you recall the scroll and last energy stone, then take the nice pillow off the bed and cut it open, shove all the gold, the scroll, and stone inside, then poof you send it away. “Now I have a pillow as well.” You say with a smile. Being a bit more powerful also seems to have increased your modesty as well. You use the sheet from the bed to craft a very simple halter top and rather tiny skirt, still far more than the nothing you were wearing.

Now the only decision is if you head straight to following the stone, or spend some gold.
