This adventure, Five Deadly Shadows, is from Dungeon #195.  A 4e adventure which I converted to 5e.  I used this to show the players two things – the larger spiritual battle happening between Amaterasu and Tsuki-Yomi vs the oni god Fumeiyoshi.  As well as the cultural difference between East and West in particular for a Japanese-analogue culture.

Apart from emphasising these powers through the adventure and making it explicit that the Five Deadly Shadows worshiped Fumeiyoshi I played the adventure as written.

Here is Naimiko Sato who was locked down and killed within two rounds – another lesson that anyone you want to last more than 1 round should have legendary resistance 🙂

I did reskin her, buffed her up and she was in the next adventure where she performed much better and was more interesting to run/fight.

Corrupting Serenity. At the start of her turn, Namiko can make a saving throw against one effect that a save can end. If she saves, the effect ends on Namiko, and she can transfer it to an enemy adjacent to her. If her saving throw fails, Namiko can still make a saving throw against the effect at the end of her turn.

Fiendish Blessing. Namiko’s AC  includes her Wisdom bonus.

Shadow Shield (1/Encounter). As a move action, Namiko can teleport up to 30 feet to an unoccupied space she can see and becomes invisible until the start of her next turn.


Multitattack (1/Long Rest). Namiko may take two actions.Oni’s Touch. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) fire damage plus 13 (3d8) necrotic damage and Namiko can slide the target 5 feet.

Beshadowed Mind. Ranged Spell Attack: +7 to hit, range 120 ft., one target. Hit: 10 (3d6) necrotic and psychic damage and the target can’t see more than 10 feet (A DC  16 Wisdom saving throw at the end of the target’s turn ends this effect).

Wu-Jen’s Prophecy (Recharge if target saves). One humanoid Namiko can see within 30 feet of her must succeed on a DC 16 Wisdom saving throw or be magically charmed for 1 minute.  While charmed the target must attack an enemy target of Namiko’s choice or suffer weakness against any other target (all STR and DEX based attack and damage rolls are halved).

Deep Shadow (Recharges when first bloodied). Namiko 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 Namiko’s next turn.  Alternatively, Namiko may use a bonus action to maintain the zone until the end of Namiko’s next turn, and Namiko can move the zone up to 20 feet.


Shadow Augury (1/Encounter). When an attack hits Namiko while she is bloodied Shadow Shield recharges and she uses it.
