Checking if unarmed then add +2 to Damage
 

I am trying to check a hero to see if they are unarmed then I want to add +2 to damage if true. I can check if unarmed by:

if (hero.tagis[Hero.EquipMain] = 0) then
if (hero.tagis[Hero.EquipOff] = 0) then

or

if (tagis[IsWeapon.wUnarmed] = 0) then

I am just unsure how to add the +2 to damage to the hero.

Which game system is this, so that I can move this post into the correct forum? The details of the answer will vary by game system.

Hero Lab 5e

I did find a bit of code that works, but it adds +2 to the Attack AND Damage. What needs to be done to it to only add +2 to damage?

hero.child[wUnarmed].field[Bonus].value += 2

******Edit******

It took a bit of searching, but I found it. The code is:

hero.child[wUnarmed].field[dmmBonus].value += 2
