The final value of your stronghold (including any sub-strongholds) determines the amount of additional [[Prestige]] you gain. The prestige bonus granted by your stronghold is shown in Table: Stronghold Prestige. The cost to increase your stronghold’s size **later** is modified by its furnishings and any other cost multipliers. >[!note] Combining Strongholds >You can combine multiple strongholds; for example, you might choose to put a library or a temple in your castle, or place a sacred grove on your house’s grounds. You must pay the cost for both. A sub-stronghold must be half the size or smaller in square feet than the stronghold in which it is placed, and must be of the same quality. > >**Always choose the most costly result for each bullet below, and the total Base Cost must be determined (based on [[Stronghold Size]]) for all strongholds before adding any multipliers.** **Math Help** A. [[Stronghold Types#Summary of Stronghold Types Table|Stronghold Type]] 1. Note the Minimum Size. 2. Note the Minimum Quality B.
