Thanks for this but we couldn't actually find where this is stated in the Windwalker FAQ?
In the Omega 3 Rulebook it's on page 37 second paragraph under the post battle abilities. It says:
OS3 Omega Master Rulebook wrote:
Note that many Post-Battle abilities are triggered by Kills or Pains. These are specific results, meaning that if an
Elimination occurs, it would not trigger one of those abilities. For example, Windwalker’s Cannibalism requires an enemy
Unit to be Killed, not Eliminated (such as via Devour, Abduct, etc.). Sleeper’s Demand Sacrifice does not protect against
Eliminations, only actual Kills, etc.
