Determining Genie Style AoE damage

Shaitan Earthblast (Combat)

Benefit: While using the Shaitan Style feat, as a standard action, you can spend two Elemental Fist attempts to unleash a 20-foot column of acid that has a 5-foot radius and erupts from a point of origin within 30 feet of you. Creatures caught in the column take your unarmed strike damage plus the acid damage from your Elemental Fist and are staggered for 1 round. A successful Reflex save (DC 10 + 1/2 your character level + your Wis modifier) reduces the damage by half and prevents a target from being staggered

I’d like some clarification on what does and doesn’t affect “unarmed strike damage”:

  • Bonuses from class skills? (such as a Fighter’s Weapon Training)
  • Enhancement bonus from magic items? (such as a +2 Amulet of Mighty Fists)
  • Special abilities from magic items? (such as a Shock Amulet of Mighty Fists)
  • Damage or other effects from feats? (Weapon Specialization, Power Attack, Bleeding Attack, etc.)

Obviously this question extends to all the Genie Style AoE attacks.
