I think there's an old post around here that does the math, but dual-wielding is pretty much always a better idea than using a shield, since you can block attacks with weapons anyways.

Don't eat so much. Being too full abuses your Agi and you don't want to have it too low.

Also, you seem to have several blink dog corpses. Let then lie on different floor than you currently are, they won't rot, then once you're not satiated, eat several of them. You will get TeleControl, awsome if you have some scrolls or wands of teleportation.

Try buying some food from the shop in Attnam. They have enough bananas for everyone (who can pay).

You start with some gold, so if you don't spend it all in New Attnam (yeah, damned leprosy), you can go shopping in Attnam. Or just sell something.
