So, we tried to do this the other day, and Desumo won't change to Rabidus. We did the whole get all the gems thing, made sure the message for desecration didn't pop up, were on the pads in time, and as far as I could tell did everything correctly (if the video's and various strats I've read we did anyway). But he would never respawn as Rabidus. Is there some other trick? Is it a time thing? Is it just buggy? Anyone know?
