Kill Greyoll without status effects
For this square you must kill Greyoll, the big old white dragon next to Fort Faroth, without using any status effects directly on her. That includes Bleed, Frost, Rot, and Poison.
There are two main ways of killing Greyoll expediently without using status effects on her. The first is to kill five of the smaller dragons that are around her, as killing one reduces her health by one-fifth of its total. You can use status effects on the smaller dragons.
The second way involves using Black Flame incantations or Ashes of War, as Black Flame is not a status effect but deals percentage-based damage, making the task significantly easier. However, finding Black Flame incantations or Ashes of War depends on the weapon randomizer.
Greyoll does not count as a boss at all.
