How it works
The number die picks the slot. The element die is compared to the stored memory element from last turn on the same wheel as Sangam: Vayu → Agni → Prithvi → Jal → Vayu.
The card in the struck slot is just the payload. The interesting part is the relation between last turn's element and this turn's element.
Outcome legend
PURE: same element, blank element, or no memory. Card fires at ×2.
FEED: current element feeds the memory element on the wheel. Card fires at ×1 and the current element's verb happens.
SMOTHER: memory feeds the current element. Card fires at ×0.5, then its element is converted to the current element.
CLASH: opposite sides of the wheel. Card fires at ×1, is exhausted, you take 3, and next turn's energy is +2.
Element verbs on FEED
Agni: global Heat +1 for the rest of combat.
Jal: apply Weak and gain 4 Block.
Vayu: rotate all cards one slot right.
Prithvi: next turn your first reroll is free, and Block does not decay on the enemy turn.
Akasha: Shunya fires plain at ×1, clears memory and Heat, and the churn resets.
