“	The longer a Flum Ox lives, the deeper its communion with the Elements grows, and for an exceedingly rare number, this mystical union pushes the Monster to some natural extremes. Venturing into isolation, Epic Flum Oxen establish a hermitage where the indigenous overgrowth is allowed to completely encroach and grow wild. In this bony, brambly hideaway the Monster meditates, ruminates, and facultates amongst its cohabitants, taking on their nascent characteristics. Its branched horns become a knotted, tangled mess, hooking and twisting together. Its body wrapped in a cocoon turns mossy and brackish, and the untamed growth promoted within its body triggers bony eruptions forming osseous tines. The wild and unkempt nature of Epic Flum Ox belie their eremitic ways. Having achieved the apex of enlightenment, these long secluded Monsters return to broader Monster communities, bringing with them an unmatched sense of balance and harmony. Though, some have been known to return a bit early, needing a bit of help getting their horns untangled.	”

Description[]

Epic Flum Ox is a Quad-Element Epic Fire Monster that is found on Bone Island and Amber Island. It was added alongside Epic Bleatnik on October 15th, 2025, during version 5.0.0. As an Epic Monster, it is only available at select times. When available, it is best obtained by breeding Plinkajou and Kayna. By default, its breeding time is 1 day and 13 hours long. Epic Flum Ox has the best Coin production on Bone Island, with a rate comparable to Rare Gnarls (though Rare Gnarls takes up more Beds). Also note that Epic Monsters cannot breed.

On Amber Island, Epic Flum Ox can only be obtained by successfully evolving a Flum Ox or a Rare Flum Ox that is at least level 4 via the enhanced Crucible. Its successful evolution time is 1 day and 13 hours long. Epic Flum Ox has a high Relic production compared to other Monsters on Amber Island.

Likes[]

Every Monster has different things that they like. For every unique object that they like that's placed near the Monster, the Monster's happiness will increase by 25%. Placing more than one of the same liked item near a Monster won't increase its happiness by an additional amount. If there's a Unity Tree or a Primordial Monster of the same rarity on the Island, items don't need to be near the Monster. Below are the things liked by Epic Flum Ox:

Note: Incisaur is only obtainable for a limited time, and it may not be possible to get Epic Flum Ox to 100% happiness. Also, on Amber Island, all of Epic Flum Ox's likes are only obtainable for a limited time. Amber Vessels must be revitalized before they count towards Epic Flum Ox's happiness.

Earning Rate and Maximum Income[]

Notes[]

Epic Flum Ox was the last Quad-Element Epic Fire Expansion Monster and the last Quad-Element Epic Fire Monster overall to be released in the game.
- As such, Epic Flum Ox was also the last Quad-Element Epic Fire Expansion Monster to release on Bone Island.
Epic Flum Ox's elements are Air, Earth, Water, and Fire. These four elements were proposed to be the "roots" of all matter by ancient Greek philosopher Empedocles. As such, their horns are tangled up, similar to roots of a tree.
