Description: You will receive a world message saying "You hear the sound of trumpets in the distance" or something to that effect which will indicate when she has spawned.
The trumpet message is big and blue, easily distiguable from the white messages as regular fairies die. She spawns right over the well and can't get pulled off. She will keep nuking until you move out of her range.
"Chargeting teh ewll" with only half a group is not recommended. =)
