Usual Tactics

The Crimson Sphere Ooze is a mobile and aggressive predator. It uses its Rolling Charge ability to quickly close the distance with its prey, inflicting damage with both its rolling impact and the acidic residue it leaves behind. Its amorphous form allows it to navigate terrain and obstacles with ease, making it a challenging foe to evade.
