Parson is a heavy unit. Dwagons can't lift heavy units.
Hence the gambit with the promotion of the hobgobwins to knight, because a hobgobwin knight is a heavy unit (while a normal hobgobwin isn't); so they would drag their dwagons down and land out of turn.
The non-hobgobwin units had to butcher their dwagons to land, which is why they have decrypted dwagons in the first place.
