If you could have Final Fantasy spells...

[Eiko Guy]

Haste, Slow, Stop, life, death, all elementals duh and ultima.....silence, drain, sleep , petrify.

I could make my own army of me. I would have auolife so i could be immortal. MUAHAHAHHAHAH

[Zeromus_X]

I suppose Haste, Slow, and Stop would be pretty fun. Although, any number of the spells would be quite convenient to have around.

[Snap Jumper]

With winter coming, Firaga would sure be nice to lower the gas bill. I'd also try casting L2 Old (FFV) on people that refuse to grow up.

[Nifleheim7]

Life and Death. Oh, the fun you could have with those two.

True.

[Araciel]

mini. and i'd cast it on my penis.

[blackmage_nuke]

mini. and i'd cast it on my penis.

Wouldnt it be more fun to use quake?

[Gilthanes]

Power of Life and Death is so cliche. If I had to choose 1 spell from FF series to have... hmmm

In terms of usefulness to the world, Esuna could likely be the ultimate spell to have for Humanities sake, assuming it did indeed cure any and all ailments.

In terms of coolness tho, nothing quite like time magic, Stop,Haste, Float, etc

Easy, I want "reset," from FFV. That way I can say or do absolutely anything without fear of the consequences. If it turns out I said or did something bad I can bust out reset and begin the encounter over again. Someone bothering me? Punch him in the face and hit reset. Strike out with a girl? Hit reset and try another approach. Not sure how someone will take a startling revelation of character? Test it and and reset if they make a weird face. Drop a plate? reset! Take 20 minutes to help someone at work, hit reset after I've solved the problem and do it again in 10 seconds now that I know the answer. You get the idea.

My 2nd choice is sleep so I can cast it on myself and sleep whenever I want. My current relationship with sleep is based solely on abuse =(

[Necronopticous]

Pact with the Magus Sisters.

Sup' Mindy?

[Marshall Banana]

If I knew Cure, Tiki and I would never have to visit a doctor again.

[Masamunemaster]

I would want one of these two
Invisible- so I could escape eveyone
Reverse- so pain would actually be pain and love would be love

[ReloadPsi]

Haste
Hastega
Slow
Slowga
Regen
Stop
Wind-element spells (Possibly)
Teleport/Warp/Exit (Any one that does a complete escape from either a location or a battle, not a partial backtrack, but they've all had each of those names at least once before)
Return/Reset
FF5's Mute-everything spell
All levels of Demi
Reflect (Maybe)
Quick
Comet
Meteor

In other words, the entire Time Mage repertoire but replacing all the Earth spells with Wind because Wind is my favourite element :P (Okay, so Time Mages don't necessarily ever have any Earth spells but FF8 classes them as Time Magic, so...)

Anyway, battle plan if attacked in the street.

1: Stop
2: If Stop didn't work, Quick, Regen, Slow
2: If Stop did work, Quick, Regen, Haste
3: Quick, Slow (if Stop actually worked so that they'll be Slow once it wears off), Comet (or Attack if I happen to have a weapon close to hand that doesn't suck), attack again if Slow was already cast earlier

This is why Time Mages are awesome, it's just a shame their attack power sucks so hard. If they were as strong as Tidus was in FF10 they'd be amazing. I guess I'd also dabble in White Magic just in case.

[Mirage]

I'm going to go FFVI on this one. Cure 3, Life 3, Haste, Quick, Ultima and Osmose would all be my spells of choice. I could explain why, but I think that's obvious.

Yes. But you should get some Life 2 as well.

[blackmage_nuke]

I would choose reflect so i can now destroy you all!!!!

[The Last Oath]

Auto-Life .. And all the status changing magics with Esuna and Dispel
