Overbite (3.5e Spell)

''As you turn from your victorious battle looking to find a new foe, you come face to face with a giant black void that promises doom. In the next instant, you are swallowed by the blackness and feel the unique sensation of being crushed and burned simultaneously.''

Upon completion of the spell, the caster creates a portal lined with ferocious teeth that swells to the size appropriate for the target as designated by the caster. If the target fails the ensuing Reflex save, they are swallowed by the portal, which closes and traps them inside an extra-dimensional ‘stomach’ for the duration of the spell. While trapped inside, the target is treated as within an antimagic field, and also takes 1d6 damage per caster level each round. Half of this damage is acid damage while the other half is crushing damage. For every three points of damage dealt to the target in this fashion, the caster is healed 1 point of damage. The caster cannot be healed beyond their normal hit point total and does not gain temporary hit points from this effect.

The stomach has five hit points per caster level and an Armor Class equal to 10 + the caster's level, but may only be attacked with a light slashing weapon or similar equivalent. If the subject manages to deal the stomach’s full hit point total worth of damage in a single turn, they are freed from the spell’s effect.

If the subject succeeds on the initial Reflex save, they instead take 1d6 points of damage per caster level from the gnashing ‘jaws’ of the portal as it closes, but suffer no other ill effects.
