Chromatic Bulwark (Green)

Protective Aura. All friendly creatures within 10 feet of the Chromatic Bulwark gain a +1 bonus to their AC while it is conscious.

Multiattack. Chromatic Bulwark makes two longsword attacks. It can replace one of these attacks with Reflective Shield.

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 4) slashing damage.

Reflective Shield. Chromatic Bulwark raises its shield, creating a shimmering barrier. Until the start of its next turn, it gains resistance to bludgeoning, piercing and slashing damage. When a creature within 5ft. attacks the Chromatic Bulwark while this shield is active, the creature takes 5 (1d8) bludgeoning damage.

Tail Swipe (Recharge 5-6): Chromatic Bulwark sweeps its tail in a wide arc. Each creature within 10 feet of the bulwark must succeed on a DC 15 Dexterity saving throw or take 14 (2d8 + 5) bludgeoning damage and be knocked prone. On a successful save, the creature takes half as much damage and is not knocked prone.

Roaring Taunt (2/Day). As a bonus action, Chromatic Bulwark can create a distracting presence, compelling creatures to target it. Each creature of its choice within 30 feet that can see and hear it must make a DC 15 Wisdom saving throw or use its next turn to move towards Chromatic Bulwark. This movement does provoke opportunity attacks. The creature will take the safest route and can use the disengage action if necessary. If the creature can not reach the Chromatic Bulwark with its movement and has not used the Disengage action, it must use its action to Dash.

Chromatic Resilience (2/Day). When Chromatic Bulwark takes Acid, Lightning, Fire or Cold damage it can use its reaction to halve the damage and gain resistance to that damage type until the start of its next turn.

When Chromatic Bulwark is dealt Poison damage, it can use this reaction to heal for half of the damage done instead.
