Gape of the Serpent

(Serpent Kingdoms, page 146, DnD 3.5)

[Monster]

Like a snake, you can stretch your mouth to an outlandish extent to accommodate immense prey.

Prerequisite

Swallow whole special attack

Benefit

You can swallow a creature of up to your own size category. Swallowing a creature as big as yourself, however, is a time-consuming process. Once you have established a hold against such a creature, you make a new grapple check as usual, but success indicates only that you have begun to swallow. On the following round, you must make an additional grapple check to complete the swallowing. The held creature can fight or try to break the grapple as normal while you are attempting to swallow it.

Special

Your gullet can hold one creature of the maximum size. Other maximum numbers of swallowed creatures remain the same.

Normal

Unless otherwise noted, a creature can swallow opponents up to one size category smaller than itself.
