With some completely revamped units, new leader upgrades, spellbook makeovers and some balance changes, this mod should keep things fresh and exciting.
To install the mod, simply extract the Globals folder into your Disciples 2 Rise of the Elves folder and overwrite everything.
Make sure you save a backup version of your original Globals. You will need this if you ever want to return to the original game, and for the Elven campaign, which has a known issue. Read the mod summary for dealing with the known issue.
