Pandemonium!
A terrifying environment that actually nullified all mana and health Regeneration as well as drastically reducing the reserves of both health and mana, along with a myriad of other terrifying effects as they would make any common being perish in a matter of seconds.
This was especially so when faced against enemies as mana was more often than not the life line of all beings. If one could not regenerate their mana, how could they fight? The moment their reserves ran out- they were marked for death!
This was what the existences surrounding Noah in this small cluster of Pandemonium knew, and it was why they were all the more surprised when they saw him utilize tremendously high taxing abilities that called upon the essences of many daos and Laws to bring forth a terrifying ability.
