In the previous series, Ultima rules, yes. (Except final fantasy tactics, it sucks ><)
Some people said Holy and Meteor is great too, yea, great except in FFXI.
FFXI in a pt:
(WHM) HolyyyyWHM starts casting Holy on a mob...
Holy hits the mob for 50 damage.
(WHM) omg... this is badWHM starts casting Holy on another mob...
Magic Burst! Holy hits the mob for 226 damage.
(WHM)I give up.... 220ish damage even on MBs-----------------------------------------------------------
FFXI Promethia fight: (actually behemoth cast this too. Since I never fought him but I did fought Promethia, so...)
Promethia starts casting meteor...
(PLD) omg
PLD is too far away
(PLD) ha ha ha!!
Promethia starts casting meteor...
Meteor hits PLD for 800 damage
(PLD) Still heavy damage.... but no match to my galka HP!! (this pld have 1700 HP)
In my view, i agree with ultima for as best spell in the most FF series.
For the skill, I love Final Fantasy Tactic's Hamedo, which will hit the one who attack our character before he attack us, stunning the attacker's attack for that turn. Too bad this doesn't work with range attacks and magics... crying
