A nice wealth of tips there by kazuma
Heres one...
If you raise a mag to level 200 and fancy a different mag, as long as it's not special or been kitted, you can change it by giving it to a different ID or Class to feed.
I'll give you an example, I raised a Kama with the stats POW > DEX > MIND
I didn't like the Kama, so I gave it to many different Classes and IDs to see all the possible other outcomes, and I found I could raise a Marica, Kama, Naruka and Varaha all from the same stats.
Be warned, if you re-feed it at level 200, it will change back to the original mag you were stuck with.
Mags evolve when fed at every level that ends with a 5 or a 0.
