Character Variables for Use in Formulae

The following values can be used in various rolls, most are applicable to the various formula fields in powers and apply based on the power itself, or refer to the weapon that the power is using.

Those related directly to an actor can also be used in effects.

Custom Variables

It is possible to create a custom @variable that can be referenced in powers attack and damage rolls and other roll formula.

To do this create an effect with a change that begins with @, so @MyCoolBonus

Note if using auto complete for inline properties you will need to close the auto-complete dialog.

You can then reference @MyCoolBonus in powers and in custom power/weapon effects (see @UUID[Compendium.dnd4e.manual.JournalEntry.VLRhDKYMBtS0MrJa]{Effects}). Not that you *cannot* reference these variables in standard effects that modify an actor's stats, because they are only recognised in the 4e-specific handler code used for power/weapon effects.
