Was talking with some friends the other night about what could be added from previous FF games and "Magic Sword" came up. When I say magic sword, I mean FF9 style where Vivi powers up Steiner's sword, which then unleashes a powerful elemental attack (Details).

When I consider what it could be like in FFXIV, I imagine a mage class (thaum or con with respective elements) nuking another melee character, giving that character the ability to do some good elemental damage for a single attack or short time (not talking FFXI en-spells here). It would need to be implemented in a way that all classes enjoy the strategy, for instance:
  1. CON/THM nukes another character, giving them said elemental power up
  2. Nuked player performs an attack (auto, or WS?) that performs extra elemental damage
  3. Nuked player receives enmity for most or all of the damage

A lot of these idea threads are pretty stupid (and something like this might be coming back with battle regimens?), but I was curious what other people thought.
