  • Non-Euclidean Shielding may be applied when a Dunlain Reaper uses its SUSTAIN DAMAGE ability.
  • Non-Euclidean Shielding applies whenever hits are produced. This includes hits produced by BOMBARDMENT and SPACE CANNON abilities.
  • If there are multiple hits that can be cancelled, then the Letnev player must cancel two hits whenever one of their units uses its SUSTAIN DAMAGE ability; they cannot cancel just one.
  • Say the Letnev player has exactly one hit produced against them remaining, and one of their units uses its SUSTAIN DAMAGE ability to cancel it. If additional hits are produced against the Letnev player’s units, such as with the Reflective Shielding action card, the Letnev player cannot retroactively use the previous use of SUSTAIN DAMAGE to allow Non-Euclidean Shielding to cancel a second hit.
