Floral Camouflage. While the mammoth remains motionless and is lying down, it is indistinguishable from a large moss-covered boulder.
Sticky Moss Exterior. When a creature hits the mammoth with a melee weapon attack, there is a chance it becomes entangled in the sticky moss that coats the mammoth. The attacker must succeed on a DC 13 Strength saving throw, or the weapon becomes stuck to the mammoth’s moss. If the weapon’s wielder can’t or won’t let go of the weapon, the wielder is grappled while the weapon is stuck. While stuck, the weapon can’t be used. A creature can pull the weapon free by taking an action to make a DC 13 Strength check and succeeding.
Actions
Multiattack. The mammoth makes two attacks: one with its trunk slam and one with either its gore or stomp.
Gore. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) piercing damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw or become infected with vicious parasitic spores.
The effects of these spores go unnoticed until three days have passed, after which the creature will begin to grow moss around the source of the wound. On each day following, the moss continues to spread and reduces the maximum hit points of that creature by 5. When the creature hits 0 maximum hit points they die and are consumed by the moss.
This moss can be destroyed via greater restoration or by exposing the infected creature to continuous powerful heat for 24 hours which causes the moss to dry up and die off.
If an infected creature is ever within the range of a Plant Growth spell, the moss spreads explosively and consumes the creature instantly.
Stomp. Melee Weapon Attack: +10 to hit, reach 5 ft., one prone creature. Hit: 29 (4d10 + 7) bludgeoning damage.
Trunk Slam. Melee Weapon Attack: +10 to hit, reach 10 ft., one creature. Hit: 21 (4d6 + 7) bludgeoning damage, and if the creature is of size Medium or smaller the mammoth can choose to either throw the target or slam it to the ground. If the mammoth throws the target, it lands in a space of the mammoth’s choosing within 30 feet and must succeed on a DC 18 Dexterity saving throw or fall prone. If the mammoth slams the target, it takes an additional 7 (2d6) bludgeoning damage and is knocked prone at the mammoth’s feet.
