JJK Ten Shadows

A ROUNDS card mod inspired by the Ten Shadows technique from Jujutsu Kaisen.

How it works

Pick Unlock Ten Shadows. You get the Divine Dogs right away, and shadow cards (Nue, Toad) can show up in your picks from then on.
Hold J (controller: D-pad Up) to open the wheel around your character. Point at a shadow with the mouse (controller: right stick) and release to select it.
Press K (controller: Y / Triangle) to summon the selected shadow.

Divine Dogs

A pair of black and white wolf-like shikigami, given from the start. They excel at tracking, scouting and physical combat.

Stat	Value
Dogs at once	2 (one black, one white)
Dog health	200
Bite damage	25 (once per second)
Dog lasts	30 seconds
Summon cooldown	8 seconds

The first summon brings the black dog; once the cooldown ends, the next brings the white dog. With both out you can't summon more until one is gone.
Tracking: they sense enemies up to 30 units from you and hunt them down.
Scouting: the enemy a dog is hunting gets a marker on your screen. When that enemy is off-screen, the marker sits at the screen edge and points toward them.
They walk the map like real animals: they follow behind you, jump up ledges and over gaps, chase enemies and pounce on them.
Shadow travel: if a dog gets stuck, falls off the map or ends up far away, it sinks into a shadow and re-emerges on the ground near its target or near you.
Enemies can shoot them; below 30% health a dog runs back to you and heals while it stays close, then rejoins the fight at 70%.
All dogs vanish when a point ends.

Divine Dog: Totality

If the White Dog is killed, its power merges into the Black Dog. If the Black Dog is out it transforms on the spot; otherwise your next summon is Totality. For the rest of the game you summon a single Divine Dog: Totality instead of the pair.

Stat	Value
Dogs at once	1
Health	450
Bite damage	45 (every 0.75 s)
Size	1.4x a Divine Dog
Speed	+20%, dashes more often

A dog that simply runs out of time does not trigger Totality. A new game gives everyone their pair back.

Nue (Rare, needs Unlock Ten Shadows)

A large, winged owl-like shikigami with a human-like face. It carries you through the air and coats its wings in electricity to shock and stun enemies.

Stat	Value
Shock damage	20
Stun	0.75 s
Flight	3 s per full meter (refills on the ground)
Nue health	150
Nue lasts	20 seconds
Summon cooldown	12 seconds

Air transport: while Nue is out, hold jump in the air and Nue grabs you and flies you wherever you steer (movement keys / left stick). The blue bar under Nue's health shows the flight meter.
Electric wings: Nue swoops at enemies within 14 units of you, shocks them (damage + stun), then circles above them until it can shock again (every 3 s).
While it is carrying you, Nue doesn't attack.

Toad (Rare, needs Unlock Ten Shadows)

A large toad with a long, powerful tongue that restrains enemies.

Stat	Value
Tongue range	10
Hold	1.5 s (yank in, then held)
Tongue damage	10
Toad health	250
Toad lasts	20 seconds
Summon cooldown	10 seconds

Toad sits on the ground where you summon it and turns to face enemies.
Any enemy that comes within 10 units gets lashed by its tongue: yanked in front of Toad's mouth and held there for 1.5 s (they can still shoot). It grabs again 4 s after letting go.
Coming later: grabbing allies out of danger, and fusing Toad with Nue (The Well's Unknown Abyss).

Multiplayer

Works in local and online multiplayer. Every player in an online lobby needs the mod installed. Each shadow is controlled by its owner's game and mirrored to everyone else, so on other players' screens it can trail its real position very slightly. Hunt markers are only shown to the dogs' owner.

Known limitations

The buttons are fixed (J / K on keyboard, D-pad Up / Y on controller).
