Tutorial/Kipumaki Cliff Where the Wild Hunt Lurks...

The Kipumaki Cliff area is currently occupied by the Wild Hunt. Under the giant Evil Eye, the corrosion of the Abyss runs rampant.
A prolonged exposure in this area leads to the continuous accumulation of Abyssal Decay. Once Abyssal Decay reaches its limit, characters will continuously lose HP until they are incapacitated.

Light the Oath Lanterns left behind by the Lightkeepers with a kuuvahki current to reduce the Abyssal Decay already accumulated.

In addition, having a party with a somewhat high Moonsign Level can slow the accumulation rate of Abyssal Decay.
