Its very difficult, my party only has average of 8 hp each and even wolves can kill them, any hints on beefing up quickly?

First, try to have a balanced party. It is good to have at least two fighters to put up front, a thief to find traps, a cleric to heal, and a mage or two. Go to Pomab's emporium to buy the best armor and weapons you can for the fighters (they will be the ones to bear the brunt of enemy attacks). Be sure to get missile weapons (darts, slings, or bows) for the support people. A typical battle against wolves would involve two heavily armored warriors moving forward with swords or axes to engage the wolves while the other characters pelt the canines from a distance with bullets and arrows (and spells too, if necessary). Make frequent use of the [space] bar to pause combat so that you can monitor your characters and perhaps issue them new orders. You will find that managing battles becomes much easier as your gain familiarity with the game. Good luck!
