Spellcaster is a special ability of some creatures, which enables them to cast a spell during combat. Creatures can cast the spell on their own turn during combat, and typically they use their chance to act to do so. However, Enchanters are the exception to this rule. They only cast mass spells and they do it in the beginning of their turn and do not lose their chance to attack in the process.
Perhaps the most renowed spellcasters in 埃拉西亞的光復 version, are the Master Genies, who can cast several different spells. The expansion 末日之刃 introduced Faerie Dragons and Enchanters, who also can cast several different spells, as well as Storm, Ice, Energy and Magma elementals, who can each cast protection from their own school of magic.
