Warped fly

Warped flies are monsters found at the bottom floor in the Lumbridge Catacombs after the completion of The Blood Pact quest. However, these should not be underestimated because their speed is fast. They primarily attack using ranged.

Warped flies can also spawn in the Nemi Forest on Mazcab. These flies, however, scale to the player's level.
