Monstrous Mandrill and the Mischief Monkeys

Monstrous Mandrill and the Mischief Monkeys is a quest with a boss called the Monstrous Mandrill. Defeating this boss will unlock the monkey Quest Pet. The quest scroll can be purchased from the Quests shop for 4 gems.

The Monstrous Mandrill's  HP pool (400) makes this a short length quest and its strength multiplier (1.5) makes this an easy quest. Without using Warrior or Mage boss damaging skills, a four-person party can typically finish this quest in between one and two weeks.

Description
The Sloensteadi Savannah is being torn apart by the Monstrous Mandrill and his Mischief Monkeys! They shriek loudly enough to drown out the sound of approaching deadlines, encouraging everyone to avoid their duties and keep monkeying around. Alas, plenty of people ape this bad behavior. If no one stops these primates, soon everyone's tasks will be as red as the Monstrous Mandrill's face!

"It will take a dedicated adventurer to resist them," says @yamato.

"Quick, let's get this monkey off everyone's backs!" @Oneironaut yells, and you charge into battle.
