Like some strange tentacular shark, the tadhemoth darts towards its prey. Its eye fixes straight ahead, and its tentacles lash out at the frightened target, grabbing and pulling its meal towards its fanged maw.

Tadhemoths hunt with slightly more intelligence than their more juvenile counterparts. Though they will still attack anything they think they can eat, they are more stealthy and cunning in their attacks. The tadhemoth’s preferred mode of attack is to approach potential prey from behind.

Once prey has been ensnared and swallowed, the tadhemoth will attempt to break off any combat, retreating to deeper waters to swallow and digest its meal. As tadhemoths fight only for food, they break off any combat in which they take more than 50% of their hp in damage. Tadhemoths rarely attack entities that they remember as seriously hurting them, preferring to seek easy prey.

Amphibious (Ex)

A tadhemoth can survive either in or out of water although they have more difficulty on dry land.

Slowed by Electricity (Ex)

While tadhemoths take no damage from electricity, electrical attacks other than that of a woghemoth confuse them, and they become slow for 1 round, as if affected by the spell slow.


Environment temperate marsh
Organization solitary or pair
Treasure none

As tadhemoths age, they continue to grow, reaching maturity at three years of age. A tadhemoth gains an additional HD every 3 months. As they grow, their rear fins morph into legs and their tail thickens. At 12 HD, their land speed improves to 20 ft.

After about 6 months of growth, the woghemoth enters its second larval stage, that of the tadhemoth. At this point, the pectoral fins have become stubby tentacle looking arms, and the tongue of the tadhemoth has developed enough for it to pull food into its fanged mouth.

Normally, by this stage the juvenile froghemoth has lost the ability to discharge electricity. As the tadhemoth grows, its rear fins morph into legs, its tail shortens through apoptosis, and its tentacles thicken and lengthen. A froghemoth reaches maturity by 3 years of age although the creature continues to grow all of its life.
