Traits

Amphibious Forager.
The Amebelodon can breathe air and water and has advantage on checks to detect or locate plants or animals in muddy or aquatic terrain.

Tremor Sense (30 ft.).
While in contact with the ground or riverbed, the Amebelodon detects vibrations and movement within 30 feet.

Trampling Charge.
If the Amebelodon moves at least 20 feet straight toward a creature and hits it with a Tusks attack, that target must succeed on a DC 17 Strength saving throw or be knocked prone. The Amebelodon can then make one Stomp attack against it as a bonus action.

Trample Over Soft Ground.
The Amebelodon moves naturally through mud, marsh, or shallow water without penalty. Any Small or Medium creature in its path must succeed on a DC 16 Strength saving throw or be knocked prone as the Amebelodon passes through.

---

Actions

Multiattack.
The Amebelodon makes two attacks: one with its Tusks and one with its Stomp.

Tusks (Gore). Melee Weapon Attack: +9 to hit, reach 10 ft., one target.
Hit: 23 (4d8 + 6) piercing damage. If in mud or water, it can push the target 10 feet and knock it prone.

Stomp. Melee Weapon Attack: +9 to hit, reach 5 ft., one prone or Medium-or-smaller creature.
Hit: 19 (3d8 + 6) bludgeoning damage.

Mud Trample (Recharge 5–6).
The Amebelodon moves through soft terrain in a straight line up to 20 ft., affecting any Small or Medium creature in its path. Each creature must succeed on a DC 16 Strength saving throw or be knocked prone. The ground becomes difficult terrain until the end of the Amebelodon’s next turn. This represents natural trampling, digging, and displacement of mud—not magical effects.

---

Tactics

The Amebelodon uses raw size, tusks, and terrain to dominate. It will:

• Charge through open ground to knock foes prone with Trampling Charge
• Use Stomp against prone or small creatures
• Move through mud, marsh, or shallow water to hinder opponents naturally
• Protect its herd or young, focusing attacks on the most immediate threats

It fights like a realistic prehistoric juggernaut, blending environmental control and brute force.

SPECIAL ABILITIES

Trampling Charge (Ex): If the Amebelodon moves at least 20 ft. straight toward a foe and hits with a Tusks attack, the target is knocked prone (DC 18 Strength). The Amebelodon can then make one Stomp attack as part of the charge.

Trample Over Soft Ground (Ex): The Amebelodon moves through mud, marsh, or shallow water without penalty. Any Small or Medium creature in its path must succeed on a DC 18 Strength save or be knocked prone. Terrain becomes difficult until the end of its turn.

Tremorsense (Ex): The Amebelodon detects vibrations within 30 ft. while in contact with the ground or riverbed.

ECOLOGY

Environment: Temperate floodplains, marshes, and river deltas
Organization: Solitary, pair, or herd (3–6)
Treasure: None

TACTICS

During Combat:
Amebelodons fight like massive, natural juggernauts. They charge through open terrain to knock foes prone with Trampling Charge and Stomp attacks. In marshy or muddy areas, they use Trample Over Soft Ground to hinder enemy movement and control the battlefield. They defend their young fiercely, focusing attacks on the most immediate threat.

Morale: Generally calm and deliberate, they fight fiercely when provoked or when defending a herd. They retreat only if severely wounded.

DESCRIPTION

The Amebelodon is a massive, prehistoric elephant-like animal distinguished by its broad, flattened lower tusks, which it uses to dig roots, strip vegetation, and move soil. Its thick, mud-streaked hide bears scars from riverbeds, while moss and reeds often cling to its flanks, giving it the appearance of a living island moving through floodplains. Despite its size, it shows careful social behavior and remarkable adaptation to soft, marshy terrain.

Amebelodon

This gigantic elephantlike creature has two sets of tusks, the upper pair like those of a typical elephant, and the lower pair longer, straighter, and shovel-like.

The amebelodon is a proboscidean adapted to life in swamps and rivers. It uses its shovel-like tusks to scoop up water plants which make up the bulk of its diet or to scrape bark from trees.

An amebelodon stands 10 feet high at the shoulder and weighs over 4,000 pounds.

COMBAT

An amebelodon fights much like an elephant, although its tusks are not useful in battle.

Marsh Move (Ex): Amebelodons take no movement penalties for moving in marshes or mud.

Toss Muck (Ex): As a standard action, an amebelodon can toss a tuskful of muck at a target within 20 feet. This requires a ranged touch attack. The target is blinded until it takes a move action to wipe off the muck. This ability may only be used in muddy or marshy terrain.

Trample (Ex): Reflex half DC 25. The save DC is Strength-based.

Skills: An amebelodon has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
