The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
Spells - 0.8.6.
The Shaman now has chaos aura, replacing berserk spell (since you can research it for all infantry and axe throwers or develop pyromancy spells with your hero, when playing minotaurs).
Cools spell idea, Minotaur Shaman really didnt need Berzerk spell, they already have it as an ability on most the relevant units. Its also cool that it is getting even more different than the Goblin Shaman.
Yes - that was exactly the reason why it was changed (already having it as an ability for the majority of the race).
