Every slot belongs to an element, so where you put a card decides what it does.
Four braziers have fixed elements: Agni → Jal → Vayu → Prithvi → Agni; the arrow means feeds.
Placing a card is free but locks its pairing. Same element = PURE ×2. Card feeds brazier = CHARGE ×1, brazier pays +1 ⚡ each turn until it resolves (resolving spends the Charge). Brazier feeds card = DOUSE ×½, brazier blocked next turn. Across the wheel = RUPTURE ×3, card exhausts, you take 4. Multipliers scale damage and Block only — Weak and draw are never scaled. Agni escalation is added after multipliers.
Two dice always roll together. The number die (1–4 or blank) names which brazier resolves at turn end; blank names the lowest occupied. The element die makes it STRONG (×2) on the brazier's element, or SWIFT (the next brazier clockwise also resolves, plain) on the card's element.
Energy = 1 + charged braziers. Rolling costs 1; first reroll 1, later rerolls 2. While placing, 1 ⚡ stays reserved for the roll, so paid draw and clearing a Douse need 2 ⚡.
