Black Mage - the solution for everything?

[Chardrizard]

Bosses that resist magic might be interesting. Certainly will stop the BLM Burn Mania ^.^; I always thought the idea of a boss that would 'cycle' through weaknesses would be nice (sometimes weak to magic, melee, piercing, etc.) or have adds that had different resistances.

If we had a simple situation:
Boss weak to melee
Half adds weak to magic
Half adds weak to piercing

Would certainly encourage more diversity.

You just defined Garuda. Except boss has no weakness, it takes damage from anything. But it has 2 adds which one weak to magic, one weak go melee.
