Displace and Threat ordering

Question

What resolves when enemies are Displaced, and in what order?

Answer

Each swapped pair fires Threat as it resolves, before the next pair is selected.

1. 900.22aThreat resolves once for each pair swapped, inside the swap, before a repeated Displace selects its next pair.
2. 900.22bIf either moved unit dies during that reaction window, the swap stands but no further pair is selected.
3. 900.22cA Threat reaction that itself Displaces resolves at most once per chain, so two opposing Threat lines cannot bounce a swap back and forth forever. Plain Threat reactions answer every pair, nested pairs included.
4. 900.22dThreat still fires when an earlier reaction in the chain killed one of the displaced units, because the pair event already occurred and is not retracted.
5. 900.22eKeyword auras and adjacency-derived state are refreshed immediately before the triggers, so a Threat reads the post-swap board.
6. 900.22fDisplace selects a fresh pair on each occurrence from enemies it has not moved yet this activation, so no enemy is Displaced twice by one activation.
7. 900.22gCombat Displace only swaps units with matching footprint sizes, and Bosses never move.
