The caster conjures a mouth with ragged yellow teeth into existence. A vortex within begins drawing in material in an ever expanding cone in front of it. The cone begins as a 30 foot long by 30 foot wide cone when the Maw is summoned. The next combat round it grows to 60 foot long. Each combat round thereafter the cone expands another 30' to a maximum of 300' long 300' wide.
Anything not secured is sucked into the vortex and destroyed. Any creatures caught in the area of effect need to make a Dexterity 13 save. Failure means the creature is pulled 10 feet towards the Vortex and suffers 3d6 bludgeoning damage as they are pelted by detritus. A successful save means they have grabbed onto something secure means they take half damage only, but are not sucked closer to the maw. At the beginning of it's turn, a creature that failed its saving throw may attempt again to save to prevent it being sucked closer to the Maw.
A creature that succeeded on a previous saving throw may on their turn, spend an action attempting to move at half it's movement rate to get out of the area of effect of the spell. This requires another DC-13 Dexterity Saving to successfully move. While in the spells effect, each creature will take 3d6 bludgeoning damage if they have failed their saving throw, half if they have made a successful saving throw.
Any creature or object consumed in this fashion is destroyed.
