Stoneguard

Spellcasting. The stoneguard is a 3rd-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 14, +6 to hit with spell attacks). It has the following druid spells prepared: * Cantrips (at will): druidcraft, resistance * 1st level (4 slots): goodberry, speak with animals, thunderwave * 2nd level (2 slots): hold person, spike growth

Multiattack. The stoneguard makes three granite maul attacks.

Granite Maul. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage. If the attack hits, the stoneguard may also immediately cast _thunderwave_ as a bonus action. This casting uses a spell slot, but no material components.

Sentinel. When a creature within 5 feet of the stoneguard attacks a target other than the stoneguard, it can make a single attack roll against the attacker.

Skin to Stone. When the stoneguard is attacked, it may gain resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks until the end of the attacker’s turn.
