Many thanks, Raze, for the Farmland Teleporter. I think the best solution to deal with that bug is to Marathon (From Rivertown to Verdistis then to Black Forest, activating Teleporter sites on the way). Well, at such a low level, the stamina is pitiful, the constitution is comtemptible, but this choice is better than deleting many precious Savegames.
HandEFood, I made a mistake between Spear and Staff and to my surprise, that very mistake shows me an odd fact that there is no way to improve the ability to wield a Staff. Anyway, I have found no worthy Staff (or Cleaver, bandice..).
Fighting with Spear (especially with a Tower shield) is extremely aesthetic, sadly though there are not so many good ones. Harpoon of Atlantos (of El Shrimpo) is worthless (maximum damage is 24). I get stuck with a "crack partisan" (110 maximum damage) to the near end of the game until I looted a Partisan of Forst and Vampiric Lord from the dead body of a Dragon Rider in Wasteland. It is easily seen in DD that any weapon with Frost and Life Drain is no doubt most desired ones.
By the way, why should I use Boomerang when I can throw my spear?
