### Modify Buff Parameters via XML Patch

Source: https://warhorse.youtrack.cloud/articles/KM-A-84

To alter the effects of a buff, create a patch XML file named `buff__<your_modid>.xml`. This example modifies the `crime_punishment_pillory_medium` buff to increase agility by 10.

```xml
<?xml version="1.0" encoding="utf-8"?>
<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="barbora" xsi:noNamespaceSchemaLocation="../database.xsd">
	<buffs version="1">
    <buff buff_class_id="20" buff_desc="buff_pillory_desc" buff_exclusivity_id="1" buff_id="1ab50a60-821b-4c19-ace3-c296d73566da" buff_lifetime_id="0" buff_name="crime_punishment_pillory_medium" buff_params="agility+10" buff_ui_name="buff_pillory" buff_ui_type_id="2" buff_ui_visibility_id="3" duration="2400" icon_id="pillory" implementation="Cpp:BasicTimed" is_persistent="true" slot_buff_ui_name="buff_pillory" />
	</buffs>
</database>

### Modify RPG Constant via XML Patch

Source: https://warhorse.youtrack.cloud/articles/KM-A-84

To change a global RPG constant, create an XML patch file named `rpg_param__<your_modid>.xml` in the appropriate data directory. This example sets `HerbGatherXP` to 20.

```xml
<?xml version="1.0" encoding="us-ascii"?>
<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="barbora" xsi:noNamespaceSchemaLocation="../database.xsd">
	<rpg_params version="1">
