The exit from the jungle leads to a small jungle village. The villagers keep the baddies away with an ever-burning fire. You will find a place to rest in one of the huts. If you're lucky you'll find the sword hidden in the village. Nevertheless, you will want to buy all of the Onyx armor and weapons you can (preferably everything you can wear) from the shop in the village. You next task, the volcano, is treacherous without it.
Also make sure, once again, that you have a lot of Elixirs and Holy Waters. This is especially important for the volcano, because you not only have to climb up to the top, but you have to make it back down.
