Vesk use armor in a way that complements their uniquely sturdy physiology. When wearing armor, they gain a +1 racial bonus to AC. When they’re wearing heavy armor, their armor check penalty is 1 less severe than normal.

Your drone gains an armor upgrade slot for an armor upgrade (see page 204). If you do not already have an armor upgrade to install, you must purchase one separately. You can install the armor upgrade only if your drone has enough open upgrade slots to meet the upgrade’s requirements. You can select this mod up to four times, each time adding an additional slot.

You reduce the armor check penalty of armor you wear by 1 (to a minimum of 0) and increase the maximum Dexterity bonus allowed by your armor by 1.
