The Malevolent Archdemon was considered a special kind of Shadow-type creature in the Silentdeath Jungle. Their combat ability was not to be taken lightly and they possessed higher intelligence than many other monsters. That made it very easy for them to automatically adjust and raise their own potential whenever they were forced into perilous situations. Through that, they could evolve into higher level mutant Archdemons or other existences that were even more terrifying—Miniboss level Darkshadow Archdemon.
The reason why Slayer's Heart chose Silentdeath Jungle as their destination was because there were many methods and ways to force the Malevolent Archdemons to mutate and advance into new tiers as much as they could in this area! The condition of this jungle was great for them to create even more Bosses and increase the possibilities of dropping powerful Pet Eggs!
