In AndyFall, the following improvements to the Daggerfall game have been accomplished:
Some faces and bodies have been redrawn to better fit the characters.
Some clothing and armor has been redrawn to eliminate some of the graphics shortfalls.
Some additional clothing has been added.
New icons for maps and parchments
Some clothing related bugs have been fixed.
In Castle Wayrest, the Dark Elf population has been redrawn to look like dark elves (Barenziah, Helseth and Morgiah), and the castle interior has been altered slightly.
The weapon damage has been altered: axes cause more damage.
The material bonuses have been changed to make Adamantium stronger than Mithril (as in Arena) and the materials above Adamantium have also been correspondingly increased.
The Standard Classes have had their skills shuffled around and some other minor changes, for further information see below.
These modifications become only active if the CLASS00.CFG - CLASS18.CFG files that come with the Andyfall Patch are in the ARENA2 directory. Note that these changes will also effect YOUR character when you start a new game using one of the standard classes. If you don't want this, move these files to the ARENA2 directory AFTER you have created your character. In that case only the standard-class enemies you encounter will be affected. You can remove these files anytime thus restoring the classes that come with the original game.
The Ebony Blade has changed hands, however a bug remained, causing to have two weapons in one hand, if the blade is equipped together with another one-handed weapon.
Barenziah's face matches her body.
The Angry Porcupine (a.k.a. the Flying Helm inn) has been placed in the town square of Vanshire in Menevia.
Town Guards are now on horseback (even when they enter houses to apprehend you for crimes).
A very tough enemy, the Overlord, is introduced, which replaces the standard Battlemage enemy in the game. The Overlord is basically a Battlemage with lots of hitpoints (!) and a strong physical attack, but with no more powerful magic attacks than the original Battlemage: Actually he has he same spells as the Battlemage, but far more magicka.
By default you can find Battlemages in the Main Quest-related dungeons such as Castle Daggerfall, Castle Wayrest, Sentinel palace, and Shedungent and a few other Main Quest locations. These will all turn into Overlords.
You can even start the game as an Overlord. Just use the CLASS02.CFG file that comes with Andyfall and choose the Battlemage as your class. However this must be considered as a blunt cheat. You can remove the hostile Overlords from the game anytime by removing Andyfall's CLASS02.CFG file from the ARENA2 directory. The Overlords will become standard Battlemages again, after you reload the game.
