Implant Root (Ex)

When an amerta hits with a tail attack, tiny roots implant themselves into the victim’s flesh, remaining behind and growing into thick vines within seconds. The target gains the entangled condition and takes an additional 1d8 damage per round until the vines are removed (as a full action).

Plantspeech (Ex)

An amerta can communicate with normal plants and plant creatures within 30 feet, asking questions and receiving answers from them.


Environment any forest
Organization solitary

Amerta are enigmatic and little-understood protectors of the erahthi, arising from impenetrable forests when its people are threatened or in dire need. Appearing as a twisting serpentine form of melded vines and plants resembling a dragon, the amerta is actually composed from the amalgamated bodies of thousands of erahthi and is believed to contain a gestalt of all of its constituent bodies’ experiences.

Erahthi history speaks of the amerta as much more active in the ancient past. Erahthi tales tell of dozens of amerta doing battle with ancient and unspeakable fey allies of the zahajin. Perhaps because of this tremendous activity and sacrifice, few amerta are believed to exist in the modern day.

It is assumed that amerta hibernate for long periods of time, only awakening when called by force and purpose only an amerta understands.

An amerta is generally peaceful and slow to anger, though once threatened it is relentless in its wrath. Once roused, these implacable hunters do not pause until the offending foe has been destroyed; no quarter is given to one who has slain erahthi within its sight. In combat, an amerta usually begins by flying around the foes, casting preparatory spells such as animate plants to entangle the enemy while it observes their capabilities. It then uses its breath weapon and charges into melee, using its slam attacks to further entangle foes.
