Slithering Rift

A slithering rift is so clear that it's difficult to spot. A successful DC 48 perception check is required to notice a stationary slithering rift, and a creature must be Searching to attempt this check.

A creature that walks into the rift's space might fall into any pit currently in effect due to Dimensional Pit.

Ingesting an extradimensional space like that found in a bag of holding deals 12d8 force damage to the slithering rift and its occupants.

The slithering rift then immediately uses Out You Go.

The slithering rift opens an extradimensional, 20-foot-deep pit that covers its own space and all adjacent squares unless they are walls or similarly blocking terrain.

Any other creature occupying spaces in the pit must succeed at a DC 40 reflex save or fall into the pit, taking damage from the fall (typically 10[bludgeoning|options:fall-damage] damage). Any creature grabbed by the ooze is released from the Grab and falls in, even if it was outside the pit squares.

While the pit is open, the

The slithering rift makes a single pseudopod Strike against each target within range it hasn't already Grabbed.

These attacks count toward the slithering rift's multiple attack penalty, but this penalty doesn't increase until after all of these attacks.

The slithering rift closes all pit spaces it created using Dimensional Pit, ejecting all its occupants onto the ground into random free spaces where the opening of the pit was.

Each occupant takes 9d6 bludgeoning damage (DC 40 reflex save).
