The Dinopithecus King is a fast, dangerous boss that cannot be bolaed and uses freezing, fire, damage-over-time, and explosive attacks, while the arena is filled with additional Dinopithecus and mounted creatures. Bring well-prepared Rexes supported by a Yutyrannus and Daeodon, with a Managarmr potentially helping against airborne enemies; use the arena’s cover to draw the King toward your group, then support your Rexes with courage roars. Bring the required artifacts and tributes, and don’t rely on water for a Spino’s aquatic boost.
