I just started playing PSO after my brother had deleted all of my characters, and was aiming at making a Rati mag. 5/145/50/0

Starting with a hunter mag it went varuna, then marutah with the higher dex and with the stats at 5/24/21/0 at level 50 it evolved into a Varaha. With a skyly hucast it should have evolved into an Ila.

Anybody know why the hell this happened?
