Actions

Multitattack. The golem takes two actions and uses the Pen is the Tongue of the Soul.   Oni's Touch. Melee Weapon Attack: 1d20+8 to hit, reach 5 ft., one target. Hit: 13 ( 2d8+4 ) fire damage plus 13 ( 3d8 ) necrotic damage, and the golem can move the target 5 feet.   Beshadowed Mind. Ranged Spell Attack: 1d20+7 to hit, range 120 ft., one target. Hit: 10 ( 3d6 ) necrotic and 10 ( 3d6 ) psychic damage, and the target can't see more than 5 feet (A DC 16 Wisdom saving throw at the end of the target's turn ends this effect).   Shukenja's Prophecy (Recharge if the target saves). One humanoid the golem can see within 30 feet of her must succeed on a WIS saving throw or be magically charmed for 1 minute. While charmed, the charmed creature has a choice to attack a target of the golem's choice. If unable to, the target gains the weakness condition against any other target (all STR and DEX based attack and damage rolls are halved), and Shukenja's Porpohecy recharges. The charmed target may repeat the saving throw at the end of its turn.   Deep Shadow (Recharges when first bloodied). The golem selects a point she can see within 50 feet of her and creates a shadowy area in a 15-foot cube. The area is difficult terrain for her enemies. Any enemy that enters the shadowy area or ends its turn there takes 10 necrotic damage. It persists until the end of the golem's next turn. Alternatively, she may use a bonus action to maintain the zone until the end of her next turn, and she can move the zone up to 20 feet.   The Pen is the Tongue of the Soul. Characters struck by the pen do not suffer damage but have their perception of reality “rewritten.” The DM may choose from the following confusion effects, each lasts 1 minute, and the target may make a CHA saving throw at the end of its turn to return reality to normal:

• a friend looks like a foe;
• the victim believes the battle is over;
• sees the foe as his friend;

Reactions

Shadow Augury (1/Day). When an attack hits the golem while she is bloodied, Shadow Shield recharges, and she uses it.

Legendary Actions

The golem can fold and animate origami weapons. These devices each are tiny objects with 20 hp, 18 AC, 4 STR, 18 DEX and do 3 (1d4+1) damage and suffer double damage from fire unless specified otherwise. Once an item is folded, her breath enlarges it to double size. She creates the following origami creatures in order, and then at the end of another creature's turn, assuming she survives, she starts at the top of the list. The items she can fold are:

1. Shield Beetle. Absorbs all damage from a single blow. Excess damage is lost.
2. Bee Warrior. Acts as a shield guardian.
3. Vipers. As a swarm of poisonous snakes.
4. Pinwheel. Razor-sharp blades slash at legs as it rolls along the floor.
5. Leaping Locusts. Distract one foe a round, the target has disadvantage on attack rolls and triggers Concentration checks if the target is a spellcaster.
6. Octopus. Attacks one character within 10 feet. If WIS Saving throw is made, the victim takes 4 points of bludgeoning damage, and the octopus is destroyed. If failed, the victim takes 8 points in the first round and +4 each round thereafter (12, 16, 20 etc). The target makes a saving throw to resist the attack at the start of its turn.
7. Paper Leopards. On a critical hit, the paper leopards knock the target prone.
