The new and improved Guard Armor now sporting, for some odd reason, an element of wind. The biggest addition of the Guard Armor B, however, is their Petrifying Magic Blast ability. It will damage an entire row as well as cause them to become Petrified 3 turns later if they aren't protected by the Anti-Petrify skill. Now aside from the fact that yor immortals should all HAVE this skill, in truth most fights shouldn't last 3 more rounds from that point anyway. They aren't too hard to kill, especially if you have a Machine Killer ring on; and why wouldn't you considering so many enemies at Grand Staff are of the mechanical type?
