Inspired by insane, evil wizards, a likewise insane, evil cleric got their hands on a mimic polyp and raised it to be his pulpit. From the fearsome podium, he conducted vile services often with sacrificial victims fed directly to the 'furniture'. Over time, the monstrosity absorbed the unholy power and a rudimentary understanding of religion in general. Not only can it conjure divine magic, of a sort, but it also took over the congregation once its overseer passed. Though, the sermons it and its proselytizing spawn offers are a disjointed, disturbing sort. Still, they are able to gather twisted congregations.

Shapechanger.

The mimic can use its action to polymorph into an ornate pulpit or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Adhesive (Object Form Only).

The mimic adheres to anything that touches it. A Huge or smaller creature adhered to the mimic is also grappled by it (escape DC 13). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only).

While the mimic remains motionless, it is indistinguishable from an ordinary ornate pulpit.

Grappler.

The mimic has advantage on attack rolls against any creature grappled by it.

Innate Spellcasting.

The mimic can innately cast Command (spell save DC 13), requiring no material components. Its innate spellcasting ability is Wisdom.

Righteous Aura.

The mimic gains an AC bonus equal to its Wisdom as long as it is not incapacitated (factored above).

Actions

Pseudopod.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.

Bite.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 4 (1d8) acid damage.

Disgorge the Faithless (Recharge 6).

The mimic calls forth the spirits of those it has eaten it in a radius of 10ft for 1 minute. These spirits are vague shadows with chunks of their bodies bitten away. The mimic may designate up to 3 creatures it can see that this magical ability does not affect. When an affected creature enters the area for the first time on a turn or starts its turn there, it must succeed on a DC 15 Wisdom saving throw or take 9 (2d8) necrotic damage and have its speed reduced by half until the end of its turn.
