12.6d Knockback Sequence
If knockback is caused due to the KNOCKBACK keyphrase, all affected characters are knocked back after all applicable characters have clicked their dials due to damage taken (but before the attack resolves). Otherwise, resolve the knockback when the effect specifies.
A character that is knocked back is knocked back in a direct path (called the knockback path) away from the character causing the knock back. To knock a character back, place it into the first square along the path, and then place it into the next square along the path, etc. Continue placing the character one square at a time in squares next to each other along the knock back path until one of the things below occurs that cause the knockback sequence to stop:
▪ The character has been knocked back three squares. (Note that some effects may specify a different number of squares to stop the knockback path at.)
▪ A character occupies the next square.
▪ A square of blocking terrain occupies the next square or a wall is in between the next square (If the knockback path is diagonal, two walls along the intersection that would prevent adjacency with the next square would stop the knockback path. See 16.8c).
▪ The next square would be past the edge of the map.
▪ The next square is a higher elevation than the current square.
▪ The previous square was a higher elevation.
For effects that check if a character was knocked back, they are considered knocked back if the Knockback Sequence was applied to them, even if they did not leave their initial square.
12.6e Knockback Damage
If a character’s knockback path is stopped before being placed three squares (or the specified number of squares if greater) and wasn’t stopped because a character occupies the next square in its knockback path, immediately deal that character 1 damage. This is called knockback damage.
Characters also immediately take 1 knockback damage if an elevated terrain marker they occupy is removed or destroyed, or if the last square in their knockback path was a lower elevation than the preceding square.
Knockback damage does not come from a character, and knockback damage never counts for effects that check if a character “damaged” a character. Characters with the Immune keyphrase can’t take knockback damage (see 27.7g).
An opposing character is on elevated terrain and would be knocked back off the elevated terrain, but another character occupies the square of lower elevation. Would that opposing character be dealt knockback damage?
