Suggestion: Ultima

Ultima
BLM gift, 500 Job Points
MP Cost= 999

Deals massive single-target non-elemental damage. (ie: 1/3 of 6-person meteor)
Requires: Elemental Seal.
Aftermath: Fallout.

Fallout: 60 second aura/weather around target.
Adds Ultima and 6-BLM-Meteor damage to Fallout DMG.
If 6-BLM-Meteor is cast during Fallout, aura/weather changes to "Blight".

Blight: 60 second aura/weather around target.
Adds Ultima damage to previously accumulated Fallout DMG.

etc, etc.

Maximum rotation i see for this?

1 alliance, 15 BLM, 3 others.

1 BLM in non-meteor PT uses Elemental Seal/Ultima. (50,000 DMG Fallout)
Meteor PT 1 casts Meteor. (50,000 DMG+150,000 DMG Blight)
1 BLM in non-meteor PT uses Elemental Seal/Ultima. (200,000 DMG+50,00 DMG Fallout)
Meteor PT 2 casts Meteor. (250,000 DMG+ 150,000 DMG Blight)
1 BLM in non-meteor PT uses Elemental Seal/Ultima. (400,000 DMG + 50,000 DMG Fallout)

After 3rd casting of Ultima during Blight, aura changes to Fallout, bursts and deals accumulated DMG.

Blight is there so chain-casting Ultima is not an option, since it's not a group spell.

One ultima over another adds nothing to fallout and is subject to Meteor's resistance attributes.

Sounds great, but I think in FF games where Ulima was apart of, all jobs got access to it in the form of Ultima weapons, as we did not get an Ultima line of weapons, I predict that is something that will be seen in FFXIV.

Aaah... no sandmaste. Its always been just a spell. I thought WHM have ultima in FFXI?
