Dermal Impact Assault Enhancement

Dermal Impact Assault Enhancement is a Fallout 2 Perk.
 * Requirements: This is a special Perk, which means that you can't just pick it when you level up. You can get this from doctors in Vault City, Redding or San Francisco once you learn about implants in Vault City. The implant will also require you to part with a suit of normal Combat Armor; Combat Armor Mark II or Brotherhood Armor cannot be used for this purpose. The implant costs $40,000 (discount to $30,000 with CH 6 or Barter 75%). The implantation will take 5 days. You can implant yourself with this enhancement only if you already have Dermal Impact Armor.
 * Benefit: This implant adds 5% to your Damage Resistance against normal and explosion damage. Unfortunately, it also lowers your Charisma by 1 permanently.
