C-Rogs, or area bosses for tokens?

MT-09 and Rombot are not like other area bosses. You don't get a blue message when they spawn. As a result, they will not spawn if the map has reached the maximum number of monsters on the map. You will have to kill a few monsters to check.

I know.

Kimera is an option only if you have done the Magatia quests that allow entry into the map.

Kimera is camped as hell.
