You are in shambling mound form now. You have a +4 size bonus to your Strength, a +2 size bonus to your Constitution, a +4 natural armor bonus, fire resistance 20, and resist electricity 20. Your movement speed is reduced by 10 feet. You also have two 2d6 slam attacks, the constricting vines ability, and the poison ability. You may choose to resume your normal form as a full-round action; doing so ends the spell for you. Constricting Vines: A shambling mound's vines coil around any creature it hits with a slam attack. The shambling mound attempts a grapple maneuver check against its target, and on a successful check its vines deal 2d6+5 damage and the foe is grappled. Grappled characters cannot move, and take a -2 penalty on all attack rolls and a -4 penalty to Dexterity. Grappled characters attempt to escape every round by making a successful combat maneuver, Strength, Athletics, or Mobility check. The DC of this check is the shambling mound's CMD. Each round, creatures grappled by a shambling mound suffer 4d6+Strength modifier × 2 damage. A shambling mound receives a +4 bonus on grapple maneuver checks. Poison: Slam; Save: Fortitude Frequency: 1/round for 2 rounds Effect: 1d2 Strength and 1d2 Dexterity damage Cure: 1 save The save DC is Constitution-based.
