This is some stuff i found out about Myth 2
1. The Deceiver or a warlock had a weather change spell.
2. There was a cloudkill spell
3. Dwarves had swords(daggers to humans), that were prob. removed to keep dwarves from having too much power
4. The Unit placement in many levels was altered:examples, THere was a Ghast commanding the tower in Walls of Muirthemne, Myrks and Fetch instead of a ghostly battle at the beginning of The Ibis Crown...
5. Ghasts were called Undead.
6. there were at least 3 units that were removed from the game. Pretas, a Conan(tm) type unit, and a Feeb. (or was a feeb originally what a Myrk Giant was called?)
7. Bungie mentioned a NEW fallen lord that was to join the light. Perhaps it was going to be Bonesplitter or The Faceless man that was to join the light.
8. I heard from someone that in the forge, you had to throw Soulblighters heart into the lava.
