I think it would be really cool if there were an attack and defense 'special ability' mith spell. Neither of them would boost stats so the success/fail would be on the build/bfa/bfe. The attack would be a 'total domination' set up, so if you won an attack the defender would not know who was attacking ("no one left to tell") if you failed an action the ability would be lost until fully regenerated (including from Xtal). The defense spell would be set up to where if the attacker lost, the defender gained the gold from the battle. Same as attack ability lose and ability is lost until regenerated fully (including Xtal). The spells would of course cost more to cast but could really turn wars into chaos. What does Kaw think!?
