If the outskirts is at its limit and additional monsters are added to it do they go in one by one or all at once?
Example: In our game we had an outskirts limit of four and a monster surge caused four more monsters to be drawn. Since the monster limit for Arkham was already maxed I put the four from the surge in the outskirts in addition to the four that were already there then put them all back in the cup.
My question is should I have taken them all to the cup or add them singly which would result in five going to the cup and three staying in the outskirts? I'm in favor of the latter as the terror track seems woefully underused but I hate house rules and would rather play as intended.
