Failure The creature is Frightened 1.
Critical Failure The creature is Frightened 2 and Fleeing until the end of its next turn.
The megaprimatus is among the mightiest of apes, quick to confront any perceived intrusions into its domain. With a height of 40 feet, it towers over even most giants, and is used to being the top-tier predator in the region.
While many apes exhibit peaceful or reclusive behavior, gorillas can be territorial, and the megaprimatus is especially aggressive and dangerous.
