## What it does

- This tells PCGen if the ability benefits may be stacked on one another.
- .MOD Behavior: When modifying an ability with the `.MOD` tag, given an existing `STACK` tag, the data included in a new `STACK` tag will overwrite the existing tag data.

## Example

`STACK:YES`

The benefits for this ability stack with itself if taken multiple times.

Default Value:

`NO`

.MOD Example:

Initial Ability: `CATEGORY=<category name>|<ability name> <tab> STACK:YES`

Modified By: `CATEGORY=<category name>|<ability name> <tab> STACK:NO`

Is Equivalent To: `CATEGORY=<category name>|<ability name> <tab> STACK:NO`

The benefits for the modified ability will not stack with itself if taken multiple times.
