Battlesworn, a supplement for Oathmark: Battles of the Lost Age, gives players rules for creating elite units of warriors known as battlesworn and charting their progress from battle-to-battle. In the horror and chaos of battle, the outcome can often hang on the briefest of moments. It is at these times that the actions of one unit can make the difference between victory and defeat. Wise kings know this, and realize that it is often prudent to hold their best units back until they can make the greatest difference. These elite units, called the "battlesworn", are more than just powerful combatants, they are symbols of the glory and honour of a kingdom. All young warriors hope to one-day join their ranks and add their oathmarks beside those legendary fighters. This supplement contains rules for adding elite units to your armies and charting the progress of those units from battle-to-battle. Will they grow even more powerful as they gain renown, or will they die to the last man in heroic defence, perhaps someday to rise again in time of the kingdom's greatest need? Also included is a campaign, featuring all-new scenarios, that will give your battlesworn the chance to lead their kingdom to new heights of power and prestige. A copy of Oathmark: Battles of the Lost Age - Rulebook is necessary to use the contents of this book.
