Hell's Deep Red Dungeon (Rhaskos) not revealed by Revelation Ritual
The red dungeon (owned by underlord Rhaskos) is not revealed by the Revelation Ritual on My Pet Dungeon Level 8 - Hell's Deep.
In my screenshot above I currently have the ritual active. The blue dungeon (Mira) has been revealed, but the red remains hidden in the FOW. It can be partialy revealed using Prospector (as that lights up the shrines)
