Description::As if a bipedal, intelligent rhinoceros made of stone weren’t threatening enough, this one’s horn is a 10-centimeter metallic drill. Some deity somewhere really doesn’t like you.

Combat

Trample (Ex): Rhydon can trample Small creatures or smaller. It deals 1d8+8 damage (for the sample Rhydon) and the save DC is 19.

Stampede (Ex): When Rhydon makes a charge attack, it is practically an unstoppable force. Everything in its path can either step aside (if there is room to do so) as a non-action or stand there like an idiot. If they stand there, then they may make an attack of opportunity. If that doesn't stop the Rhydon, it gets a free horn attack and may attempt a bull rush as well.

Earthquake (Sp): Once per hour, Rhydon may cast earthquake as a spell-like ability. Caster level equals hit dice, and the Save DCs is 10 + ½ Rhydon’s Hit Dice + Rhydon’s Charisma modifier.

The sample Rhydon has a caster level of 10 and save DC of 16 for Earthquake.

Scary Face (Su): Rhydon can make itself look extra fierce, and is able to make an Intimidate check to demoralize as a Swift action.

Horn Drill (Ex): Whenever it scores a critical hit with a Gore attack, Rhydon deals 4 points of Constitution damage through blood loss.

Powerful Build (Ex): The physical stature of a Rhydon lets it function in many ways as if it were one size category larger. Whenever a Rhydon is subject to a size modifier or special size modifier for an opposed check (such as during grapple checks, bull rush attempts, and trip attempts), a Rhydon is treated as one size larger if doing so is advantageous to it. A Rhydon is also considered to be one size larger when determining whether a creature’s special attacks based on size (such as improved grab or swallow whole) can affect him. A Rhydon can use weapons designed for a creature one size larger without penalty. However, its space and reach remain those of a creature of its actual size. The benefits of this stack with those of spells and effects that change the subject’s size category.

Acid Weakness (Ex): Rhydon takes double damage from acid, and gets pissed off.

Invincible Charge (Ex): When Rhydon charges, it doubles its DR and gains Mettle and immunity to critical hits. These last until its next turn begins.

Two Stances (Ex): Rhyhorn can happily move about on two or four legs. On four legs, it gains a +10' bonus to movement speeds, and all the benefits of being a quadruped. On two legs, it is able to make Slam attacks, but cannot Stampede. It can switch stances as a free action once per round.
