Special Abilities

Hunter (Ex)

When using Survival to track prey, a tremorlizard gains a +4 on its Survival check for each tremorlizard assisting it with the aid another ability, rather than the normal +2.

Martial Practitioner: A tremorlizard is an expert practitioner and gains a martial tradition and one combat talent for each Hit Dice it possesses. Tremorlizards use Wisdom as their practitioner modifier.

Snapping Jaw (Ex)

A tremorlizard’s bite has an expanded critical range of 19-20 and an x3 critical multiplier.


Environment temperate or warm forests, hills, or underground
Organization solitary, pair, brood (3-12)
Treasure incidental

The sound of scrabbling claws against stone follow this massive reptile’s darting movements.

Natural born hunters, tremorlizards track, hunt, and skulk in the underground, preying upon anything too slow or too unaware of its presence. Able to move silently when stalking, or rapidly charge down prey, a tremorlizard is a deadly foe and surprisingly agile for their size. Despite being territorial, tremorlizards are intelligent and communal creatures and respect their fellow tremorlizards’ territory. They will often socialize and exchange unusual prey as delicacies.

Tremorlizards are also unusually tolerant of those who pass through the area they have claimed as territory, provided those trespassers do not disturb or take resources the tremorlizard sees as valuable, such as various colorful ores and minerals or carefully arranged corpses being saved for a later meal.

Tremorlizards are often found alone, unless during their mating season or in the especially unique circumstance of a brood hunt. A brood hunt occurs when another tremorlizard is killed or disappeared from their territory without warning. A number of tremorlizards will gather after finding another tremorlizard has been slain or otherwise vanished and intelligently investigate, usually resulting in a bloodthirsty hunt on the tracks of those they believe are responsible.

Frilled Tremorlizards: Some tremorlizards have neck frills which they can flare. These neck frills are used to intimidate lesser creatures by attempting to appear even larger than they already are. Frilled tremorlizards gain 1 free rank in Intimidate for each Hit Dice they possess, plus an additional +4 racial bonus on Intimidate checks (the average tremorlizard having a +23 bonus). In addition, frilled tremorlizard can attempt an Intimidate check to demoralize a creature as a swift action by flaring their neck frills.


Some tremorlizards have undergone extreme changes when their underground habitats intersect with powerful sources of elemental and other magics.

Frostjaw Snapper (+0 CR)

When forced to adapt to harsh elements, some tremorlizards evolve to harness and better coexist with their homes. A common variant, the frostjaw snapper, dwells in freezing cold caverns and will flash freeze prey to preserve it.

Other elemental tremorlizard variants may exist. Replace the Frost Blast (blast type) and cold resistance 20 with another blast type that deals elemental damage and appropriate resistance against that damage. For example, the heartfire monitor would possess the Fire Blast or Searing Blast (blast type) and fire resistance 20.

A frostjaw snapper is a variant tremorlizard which exchanges talents (Scout (all)), feats (Skill Focus (Stealth), Vital Strike, Improved Vital Strike), and the bite attack trip universal monster ability for the following:
