In Equilibris, Ogres have gained many spells, some of which are quite useful. The Ogre-Mage has been given the following spells: Magic Resistance, Mana Drain, Spell Shackle, Snake Strike, and Sparks. He now has a total of 5 mana (previously 6).
The Ogre-Mage's ability has been changed from "Bloodlust" to "Spellcaster" due to the expanded range of spells.
