Reinforcements

  • Each of the following will appear in a given pattern, each starting turn 1; if a reinforcement is blocked by an enemy or there are three of the particular reinforcement present, they will appear on the next turn and the pattern will resume from there (e.g. if an Armored Knight is blocked from arriving on turn 3 but not turn 4, it will appear on turn 4 and the next on turn 6)
    • 1 Paladin from the northwest corner of the map every third turn.
    • 1 Armored Knight from the northern border of the map every second turn.
    • 1 Dark Mage from the southwest corner of the map every second turn.
    • 1 Fortress Knight from the southern border of the map every turn.
  • Note: Reinforcements are halted if a player unit reaches the spaces where they come from.
