Yutyrannus commonly roam snowy regions with Carno escorts, so keep your distance and deal with the pack before committing to the main fight. Its fear roar can make mounts flee uncontrollably and suffer a combat debuff, so use a strong, reliable mount, avoid cliffs, and retreat if your creature is affected. Ranged attacks or a coordinated group can help you wear it down safely.
