Proposal 13: Experience Points May Differ

Add the following rule:

Each time a Unit wins a combat, it gains one experience point.

Experience points may be spent on a variety of promotions. A promotion's cost is equal to its base cost plus one point per promotions that the unit already has. Promotions may be taken multiple times.

-Manuever: Base cost 2 XP. If the unit is defeated in combat, it has a 1/3 chance to survive and retreat to another adjacent square. If the unit has more than one hit point, it is automatically reduced to one hit point.
-Mobility: Base cost 3 XP. The unit's Movement score increase by 1.
-Defense: Base cost 2 XP. If the unit does not move on a turn which it is attacked, it gains a +1 Combat bonus.
-Castle Defense: Base cost 2 XP. The unit gains a +1 Combat bonus whenever it is on the same square as a friendly castle.
-Toughened: Base cost 4 XP. The unit gains an additional hit point.
-Heroic: Base cost 10XP. The unit gains an additional hit point and a +1 combat bonus.

Add the following rule to the Combat section:

Some units may survive more than one hit. This is represented by a hit points variable. Units without a hit points variable are considered to have only one hit point. If a unit with more than one hit point would be destroyed in combat, instead reduce its hit points by one.
