A teratomorph, a Gargantuan CR 16 ooze deals 4d6 with its slam. Most Large oozes do only 1d8. Black puddings do 2d6, and elder black puddings do 3d6.
Other ways of stating amorphous:
Amorphous (Ex): A gibbering mouther is not subject to critical hits. It cannot be flanked.
Amorphous (Ex): An alkilith is not subject to flanking or critical hits. It is immune to poison, sleep, paralysis, stunning, and polymorphing.
Amorphous (Ex): The gelatinous body of a xorbeast protects it from attacks against vital organs. Any critical hit or sneak attack against a xorbeast has a 50% chance of dealing damage as a normal attack.
Oozlike Immunities (Ex): Ghaunadans share many of the immunities of oozes, though they do have minds and Intelligence scores. They are immune to poison, sleep, paralysis, stunning, and polymorphing. They are not subject to critical hits, and cannot be flanked. These immunities apply in both humanoid and ooze form.
