THE CONVERGENCE

The Convergence

A dungeon crawl one-shot

Grab cards from any trading card games you have lying around. Draft a party of 3. Navigate the dungeon. Stop the Rift Lord.

For 2–5 players. Recommended decks: Pokémon (creature-heavy), Yu-Gi-Oh!, Magic: The Gathering. Any mix works. Cards are flavor — the DM interprets them.

The table needs 3 different decks to draft from.

The Convergence

Rift Dungeon
Premise

A dimensional rift has torn open. Creatures from every timeline are bleeding into a corrupted dungeon. You are champions pulled from your home universe to clear the dungeon, defeat the Rift Lord, and seal the breach.

Setup

1. Claim one of the available decks. Fan through it.

2. Pick 3 cards: 1 Champion (your best card) + 2 Support (any mix of creatures or spells).

3. Await further instructions from the DM.

⚠️ All cards in your party are face-up on the table at all times. No hidden information.
The table should have 3 different trading card game decks. We recommend Pokémon, Yu-Gi-Oh!, and Magic: The Gathering — but any mix works. Cards are flavor: the DM interprets their feel, not their printed text.
Power Tiers

The DM eyeballs every card and assigns a tier. Fast, subjective, final.

Cooldown

You cannot use the same card two turns in a row. Rotate through your party.

Resources

⚡ Grit (Creature-deck cards — e.g. Pokémon)

1 Grit per card from your creature-heavy deck in your party, +1 bonus if your Champion is from that deck. Spend to re-roll any die on one of those cards. Limited for the entire dungeon.

✦ Arcana (Spell & trap cards — e.g. Yu-Gi-Oh!, Magic: The Gathering)

Flash: One-time use. DM interprets effect, then burned.
Rune: Persistent buff. Stays active. DM interprets.

Turn Flow

① Declare your active card — Pick one card from your party. Only this card exists for the entire turn — it fights, triggers traps, and takes hits. Your other cards are resting.
② Move — 1 square, adjacent or diagonal.
③ Resolve — Flip the tile, handle what's inside using your active card.
④ Rest — Mandatory. All creatures in your party recover 2 Resolve (a creature already at 0 is gone — no recovery). During rest you may pass the DM a folded note.

Cooldown: You cannot use the same card two turns in a row. If you sent your Champion this turn, pick a different card next turn.
📝 Notes"This dungeon is unstable. During rest, you may pass me a folded note."

Peer Ahead (once per game) — Name a tile. DM rolls d6: 1–2 exact contents, 3–4 type only, 5–6 nothing. Info is private.
Lore Moment (once per game) — Request a narrative beat. DM rolls for flavor.
Combat

Your active card fights. DM draws threat cards and assigns tiers.

StepWhat Happens
RollBoth sides roll their power die. Higher wins.
DamageLoser takes 1 Resolve. Tie = both take 1.
RepeatUntil one side hits 0 Resolve.

Advantage: Thematic edge (water vs fire, holy vs undead)? Roll twice, take higher. DM calls it.

Grit + Advantage can stack. Up to 4 rolls.

The Rift Lord
