Great Form [Passive]

You grow a size category larger. {{#set:Summary=You grow a size category larger. }}

The man stood there, silent and still as the night, and then he began to glow, and suddenly he was towering above us like some terrible beast, striking down our men left and right, and before we could mount a proper defense there was nothing left of our patrol but blood and flesh splattered across the cobblestones {{#set:Quote=The man stood there, silent and still as the night, and then he began to glow, and suddenly he was towering above us like some terrible beast, striking down our men left and right, and before we could mount a proper defense there was nothing left of our patrol but blood and flesh splattered across the cobblestones }}

Prerequisite(s): Boon of Constitution, Boon of Greater Constitution

Description: While transformed, you grow to become one size category larger. A size increase affects any special ability you have that are affected by size. Increased size also affects your ability scores, AC, attack bonuses, and damage values as described below.

Double your height and multiply your weight by 8. This increase changes your size category to the next larger one. You gain a +2 size bonus to Strength, a –2 size penalty to Dexterity (to a minimum of 1), and a –1 penalty on attack rolls and AC due to your increased size.
If insufficient room is available for the desired growth, you attain the maximum possible size and may make a Strength check (using your increased Strength) to burst any enclosures in the process. If you fail, you are constrained without harm by the materials enclosing you.

All equipment worn or carried by you is similarly enlarged. Melee and projectile weapons affected by this Alteration deal more damage. Other magical properties are not affected by this Alteration. Any enlarged item that leaves your possession (including a projectile or thrown weapon) instantly returns to its normal size. This means that thrown weapons deal their normal damage, and projectiles deal damage based on the size of the weapon that fired them. Magical properties of enlarged items are not increased by this Alteration.

Special: Multiple magical or supernatural effects that increase size do not stack with this Alteration.

Table: Creature Size and Scale

This modifier applies to the bull rush, grapple, overrun, and trip special attacks. Biped's height, quadruped's body length (nose to base of tail) Assumes that the creature is roughly as dense as a regular animal. A creature made of stone will weigh considerably more. A gaseous creature will weigh much less. These values are typical for creatures of the indicated size. Most player characters are medium (indicated in green), followed by small and large (indicated in yellow). Some exceptions exist.
