Jain has an ability that gives her a movement point 'when a monster enters a space adjacent' to her. For a large monster, when do you consider the monster to enter a space? Since they "shrink" and count spaces and then expand, the monster could be considered to only enter the final space when the move is over. If it obviously has to go through one adjacent space to get to it's final destination, does that interrupt to give Jain her MP?

When they're "shrunk" they enter a space adjacent when they walk by the hero. When they expand back to normal size if they end up adjacent to a hero they've entered when they expand.

Expanding is not entering spaces. A large monster only enters the spaces its shrunken form enters- so a shadow dragon can end its move action 2 spaces away from jain, expand, and attack- it never entered a space adjacent to her.

If it wants to interrupt, however, that is different. The dragon is melee (no reach) so it cannot declare an attack action against Jain unless it is adjacent to her. It is not allowed to expand and THEN interrupt to attack, it must interrupt to attack THEN expand.

In short, it can use expansion to cheat Jain out of a Nimble if it is ending its move action. It cannot do so if it is interrupting.

Thanks for the timely responses!

Just to nitpick, Jain has nothing as a skill like this. Is the Wildlander who has it, and any Scout can use this class.

Yep. My wife is playing Jain as a Wildlander. Sorry if that was inaccurate.
