|Basic (4 pt): 33% from the bonus headshot damage is permanently applied to hitting enemies on the body. This skill is only activated by SMGs, LMGs, Assault Rifles or Special Weapons fired in automatic fire mode.|
|Ace (8 pt): 100% from the bonus headshot damage is is permanently applied to hitting enemies on the body. This skill is only activated by SMGs, LMGs, Assault Rifles or Special Weapons fired in automatic fire mode.|
Body Expertise grants extra body shot damage based on the target's headshot multiplier. The Basic version causes 35% of headshot damage to be applied to bodyshots, while the Aced version causes body shots to deal the same damage as headshots (the +25% headshot damage bonus from Perk Decks not accounted for). This skill works against all enemies (excluding Captain Winters or the SWAT Van Turret), however, it can only be triggered by using Assault Rifles and SMGs in full-auto mode, either by default or via the Auto Fire mod, LMGs and a number of Special weapons.
This skill is highly valuable for weapons with a high RoF, making them a good option for crowd control on higher difficulties (especially One Down) and quickly dealing with special enemies. LMGs with the Lion's Bipod can also benefit from this skill, thanks to the zero recoil the gun can get with it deployed.
Surefire aced is highly recommended to pair with this skill, as there will be enemies equipped with bulletproof armor vests on Overkill difficulty and above. Without it, the usefulness of Body Expertise will be diminished.
With the aforementioned skill, Body Expertise tends to work well against Bulldozers due to their resistance to body shots. Also, it can be a devastating skill with Overkill (aced) in which Bulldozers can be quickly eliminated even without the need for headshots.
