Midnight Crystal (Part 51)

Fallen Crypt was a Yellow Threat area, and Fume Throne, despite its creepy presence was a Light Yellow Threat area.

And... this place was now ruled by a Purple Threat level creature, Plague Reaper. He was stronger than anyone trapped inside Fume Cathedral, even Fog Hunter, a rather strong Light Yellow monster couldn't do anything to him.

Thus, inexperienced Phantoms or those who were in this situation for the first time might have a logical question.

Why was Plague Reaper a Purple Threat Level monster?

Plague Reaper was stronger than Gray Stalkers, Weeping Harahas, Fog Hunter, and a bunch of other Light Yellow Threat monsters. In that case, shouldn't Plague Reaper have rated as a Light Yellow Monster more, only ranking higher?

Well, the answer was quite simple.
