Uhm... you could do what pcmorris said - if you don't mind putting a permanent dent in your MAG's flawless stats
; - or you could have someone of another class/type change its form* by feeding it once. It would get its third Photon Blast with no change in attributes, and as soon as you fed it again, it would turn back into a Varaha.
*I checked the guide to see which you could get...
Type-B Hunter : Kama : Pilla
Type-A Ranger : Kama : Pilla
Type-B Ranger : Madhu : Mylla&Youlla
Type-A Force : Naraka : None (it would be Golla, but you already have that)
Type-B Force : Marica : Pilla
If you decide to do it that way and you need someone to feed it, I would be glad to help (assuming that you want Pilla; I don't have a Type-B Ranger
