is it even a good keyblade?
Not particularly. Your starting Keyblade has
Power 3 Magic 1
and this is
Power 3 Magic 2
Its really only useful for upping Aero damage and such in the first world, after that its outclassed...
And its a bit fun to use I guess, but using the all Keyblades cheat for Ventus to get it means you have Ultima and such....so its even more pointless to use.
