Actions

Multi-attack: a Dread Shambler makes two slam attacks

Slam: melee weapon attack: +8 to hit, range 5 feet, one target; hit: 13 (2d8 + 4) 2d8+4 bludgeoning damage; the target is Frightened until the end of its next turn if it fails a Wisdom Saving Throw (DC 12)

Pile of Carcasses (Recharge 4-5-6): a Dread Shambler can decompose into a pile of bones, sludge and debris and gains the benefits of the Dodge and Disengage actions until the beginning of its next turn; if it traverses a creature's space while in this form, that creature must make a successful Strength Saving Throw with a save DC 16 or take 6 (1d4+4) 1d4+4 bludgeoning damage and is knocked prone.
