If we're actually going with hemomancy, I'm just going to paste the raws for it here for everyone's reference.

To sum it all up for people who can't read raws, even though we're just a novice we are now immortal, don't have to eat or drink, can make any creature with blood bleed profusely at will, can create blood men and blood blobs to serve as evil minions from existing corpses or pools of blood, and any other abilities we care to make up for the story. Although, we're probably going to have to practice a lot to actually be able to get any good at it. That being said,
practice your hemomancy on the pool of blood until you can get the tiny blood minion to be able to hold his physical shape and function on his own. Then make him a little blood hat, blood sword, and blood shield and send him off looking for the lever. If he comes back successfully, promote him to general of the eventual kobold blood army. Then escape, sneak in the shadows, search for more blood, and generally try to remember just what it was you were trying to do in the first place. Oh, and recover your gear or find replacement gear.
