If I have 5 army units inside the stronghold, can I use a card that lets me recruit an elite there? I know cards break most rules, but not sure abot this one
You could play the card to recruit an elite, but then you would immediately need to return a unit to the reinforcements. So, you can at least upgrade a regular to an elite.
"Rage of the Dundelings" says "Recruit 2 Isengard regular units in a free region adjecent to North or south Dunland..." If Moira is captured by the FP, but there is no units there, can I recruit 2 in Moira?
You can never recruit into a settlement controlled by the opposing player. But you could recruit next door and then walk in unopposed.
