Darkvision
A monster with darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. Some forms of magical darkness, such as a 4th-level Darkness spell, block normal darkvision. A monster with Greater Darkvision, however, can see through even these forms of magical darkness.
Telepathy (aura, divination, magical)A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.
Beguiling LureA creature hit by a lophiithu's lure must succeed at a DC 41 will save or be Fascinated with the lophiithu's lures for 1 minute. On a critical failure, it can't use reactions while it remains fascinated. A creature that succeeds at its save is temporarily immune for 1 hour.
Dimensional SwallowThe lophiithu's digestive organs exist in the Maelstrom, regardless of the location of their external form. The lophiithu can swallow any number of creatures of any size. Creatures that Escape the lophiithu's stomach do so normally. Creatures that cut themselves free instead find themselves in the Maelstrom near nothing but one of the lophiithu's disembodied stomachs. When the lophiithu dies, their stomach becomes a rift connecting to their mouth, allowing a creature to return to their plane. This rift disappears after 1 minute.
At-Will SpellsThe monster can cast its at-will spells any number of times without using up spell slots.
Constant SpellsA constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
Lure WhipThe lophiithu makes a lure Strike against each creature within reach. These attacks count toward the lophiithu's multiple attack penalty, but the penalty doesn't increase until after these attacks.
Swallow Whole (attack)Gargantuan, 3d12+10 bludgeoning damage, Rupture 44 and dimensional swallow
The monster attempts to swallow a creature of the listed size or smaller that it has grabbed in its jaws or mouth. If a swallowed creature is of the maximum size listed, the monster can't use Swallow Whole again. If the creature is smaller than the maximum, the monster can usually swallow more creatures; the GM determines the maximum. The monster attempts an Athletics check opposed by the grabbed creature's Reflex DC. If it succeeds, it swallows the creature. The monster's mouth or jaws no longer grab a creature it has swallowed, so the monster is free to use them to Strike or Grab once again. The monster can't attack creatures it has swallowed.
A swallowed creature is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The swallowed creature takes the listed amount of damage when first swallowed and at the end of each of its turns while it's swallowed. If the victim Escapes this ability's grabbed condition, it exits through the monster's mouth. This frees any other creature grabbed in the monster's mouth or jaws. A swallowed creature can attack the monster that has swallowed it, but only with unarmed attacks or with weapons of light Bulk or less. The swallowing creature is Flat-Footed against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the swallowed creature cuts itself free. A creature that gets free by either Escaping or cutting itself free can immediately breathe and exits the swallowing monster's space.
If the monster dies, a swallowed creature can be freed by creatures adjacent to the corpse if they spend a combined total of 3 actions cutting the monster open with a weapon or unarmed attack that deals piercing or slashing damage.
Improved GrabThe monster can use Grab as a free action triggered by a hit with its initial attack. A monster with Improved Grab still needs to spend an action to extend the duration for creatures it already has Grabbed.

Lophiithus dwell in the deepest ocean trenches, places untouched by light, hope, or mortal comprehension. They appear to be gaping maws with distended jaws, vestigial flaps of putrefying flesh, and filamentous tentacles tipped with glowing light. Their extraplanar mouths take up most of their bodies, leaving no room for other organs, and any prey they swallow is transported to the Maelstrom for digestion.
