This patch allows one to complete Ultima IV with only one character (the PC). This is offset with increased combat difficulty, matched to the original Apple II levels.
A simple patch to allow a player to complete the game without having any NPC's join his quest. Secondly, combat difficulty, particularly damage dealt out by monsters, is matched to levels found in the original Apple II. The dos versions combat was approximately 3 times easier, at least in terms of damage dealt out by monsters.
