It appears there is a bug in Ultima 2 that has to do with vendor prices as a player approaches maxed stats. Both Charisma and Intelligence affect shop prices such that higher values should lower vendor prices. This is fine until a certain point, but after your stats are raised above a certain threshold it appears that prices skyrocket again.
Seems like there are lots of peculiarity with stats in Ultima 2, but this time this one was introduced by me. There is currently an exploit where it’s possible to max out your stats without spending any gold. This one was reported to me by a user of the upgrade.
For those who’ve attempted to play through Ultima IV with the latest U4 Upgrade (v1.2 or v1.3), you may have experienced a bug that prevented you from completing the end game. The problem hits after you answer all the virtue questions and obtain the codex, but the game appears to freeze in the middle of describing the Quest of the Avatar.
While the U4 Upgrade isn’t one of my patches, the purpose of the Exodus Project is to solve these types of problems in older Ultima games. I did some digging on this a while back when I ran into the same thing, but totally forgot about it until recently. I was reminded of it while watching Kilg0re_Tr0ut’s Twitch stream of U4, who ran into the same problem. Let’s take a look at what’s wrong.
