Great Form (Grim Alteration)
From D&D Wiki
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: Constitution Boon
Description: The grim grows to become one size category larger. A size increase affects any special ability the creature has that is affected by size. Increased size also affects a creature’s ability scores, AC, attack bonuses, and damage values as described below.
The grim doubles his height and multiplies his weight by 8. This increase changes the grim’s size category to the next larger one. The grim gains 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 his increased size.
If insufficient room is available for the desired growth, the grim attains the maximum possible size and may make a Strength check (using his increased Strength) to burst any enclosures in the process. If he fails, he is constrained without harm by the materials enclosing him.
All equipment worn or carried by the grim 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 the grim’s 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.
