Soaking up ambient arcane power, your body swells and grows. You stand as tall as a giant and are blessed with awesome power.

Effect: Your size category becomes the next larger one, such as from Medium to Large. You gain a +5 power bonus to Strength ability checks, a +2 power bonus to melee attack rolls, and a +5 power bonus to melee damage rolls.
    If this power increases your size to Large, Huge, or Colossal, your space increases to match the new size and your reach also increases by 1. If there is insufficient room for your space to increase, this power automatically fails.
    This transformation persists until the end of the encounter or until you choose to end it as a minor aciton.
