The Magician's Tower

so im having issues, max ally brownies, all kills in mmm cept battleroom/disco, all kills in steamfactory, couple kills in crystallos...and still this smurf brownie shows nothing o.O whats the magic word/key? I guess its not that big of a deal, just wanted rk3 servant for when i get lower gom procs.

on a similar note, what opens up rk3 mass rods, clear crystallos?

SoF raid progression opens it up afaik.

I've read Meldreth kill opens it up, can't be sure as I never got it.

Have to have been in task during all the events in MMM, not enough to just have Meldrath kill.
