Hello,
we had a discussion on the reinforcement rules during our last game session on saturday. Is the overlord player free to choose WHICH monster he wants to reinforce when more than one were defeated by the heroes previously.
Here is our situation: We played "Death on Wings" - Encounter 1 and overlord used Ettins (2x2) as open group. So Cave Spiders (1x1) and Ettins were in play. Rules says that overlord may reinforce 1 monster at the beginning of his turn on the entrance tile (2x2). In one turn the reanimate of the Necomancer was placed on one field of the entrance tile and all other heroes were placed on the "Path"-tile so that there were not enough space to place a Ettin. At the beginning of his turn the overlord had a master Ettin AND a master Cave Spider to choose the reinforcement from.
Now here is the question: Does the overlord has to choose the Cave Spider, because there is enough space to place it on the entrance tile? Or is he free to choose the Ettin? In this case, the Ettin would have been placed on the fire place, because this was the first empty space where the overlord could place a 2x2 monster.
