Orkell the Swift 's heroic feat says "Use during your turn, while you are knocked out, to preform a stand up action. Then you may either recover all (heart symbol) or meve each monster adjacent to your figure 1 space. You may still perform 2 actions this turn." does orkell get to use the squishy affect that the overlord gets while moving? I.e, expand as if Orkell was the ol? The rules of core were ment not to have such abilties. please present a good argument because my ol is convinced orkell can't.

Heroes move large monsters exactly like the OL does. This means the hero chooses a space that the monster occupies to shrink then monster, the moves the monster the number of spaces he is allowed by his ability, and finally expands the monster from the new position.

There are a number of abilities that allow heroes to move monsters: Astarra's Heroic feat, Orkell's Heroic feat, Crossbow, Leather Whip, etc.
All these work as described above.

I concur with Sadgit. The large monsters move the same way regardless of who is controlling the movement. The only difference is who is making the decisions (in the case of Orkell's feat, that person is Orkell).
