From D&D Wiki
Lemma Vissiv, Greater
large celestial, any alignment, most often neutral
Skills Arcana +4, Deception +5, Insight +6, Perception +6, Persuasion +5
Sense Magic. At all times the greater lemma vissiv senses magic within 60 feet of it. Powerful or continuous uses of magic (as well as large, magical locales) can be detected from even greater ranges (at DM's discretion).
Shapechanger. The greater lemma vissiv can use its action to change its general layout and proportions. If it so chooses it may grant itself a new natural weapon (talons, a club-like tail, etc.) its limb attack now does 11 (2d6 + 4) of either bludgeoning, piercing, slashing damage. Alternately, it can give itself a new movement type of its choice (swimming, climbing, flying) at its base move. In lieu of giving itself a new movement type, it may increase its base speed to 50 feet. It may only use one of these effects at a time.
Everchanging. Lemma vissivs are immune to any magic that alters their shape, size, or form.
Dream Walker. Once per day the greater lemma vissiv may use its action to travel between the mortal world and The Dream.
Bashing Limb. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 8 (1d8 + 4) bludgeoning damage.
Malleable Clutch. If the greater lemma vissiv isn't using its shapechanger feature to alter its damage and damage type, the target of its bashing limb attack is grappled (escape DC 14) if it is a Large or smaller creature and the greater lemma vissiv doesn't have another creature grappled.
A more powerful form of the lesser lemma vissiv, greater lemma vissiv are found throughout the deeper regions of The Dream. Formed when lesser lemma subsume some source of significance or when two fuse together. These Dream creatures command their lesser kin.
