Stragglers to the Harvest
In the chaotic conditons of the Godswar, command and control sometimes take second place to getting the job done yourself. In this scenario, the warlords arrive at the battle first, seeking to gather Stratis's Divine Sparks as best they can, while the rest of their warbands straggle onto the field.
Use the rules for the Blood Harvest scenario as detailed on pages 12-13 of Blood and Darkness, with the exceptions listed below.
Before the battle, and at the end of each turn, the younger player rolls a d20 to determine the number of "stragglers." Both players add the result of that one roll to their personal reinforcement pool. The first time a player activates a model that turn, he must decide whether or not he wants to use his reinforcement pool to bring models from his warband onto the table.
If a player wants to bring one or more models onto the table that round, immediately reduce his reinforcement pool by the cost of the models he wishes to bring onto the table. He may then place each newly arriving model anywhere he wishes within 1" of his board edge, so long as the models are at least 3" away from any enemy models. The newly arriving models count as part of the player's warband that turn. For example, if you start the turn with just your warlord and two Dwarf Zealots in play, and then you use 10 points from your reinforcement pool to bring two Dwarf Legionnaires into play, this counts as having 5 models in play at the start of the turn, and you can activate two models at a time.
If a player chooses not to bring any models onto the table that round, or if his reinforcement pool isn't large enough to pay the cost of his models that are still out of play, the player playsthat round with the forces he already has on the table.
