[RPG] A Pathfinder creature from the Cthulhu thethos

Yes, the Lamia Matriarchs (prominently featured in Rise of the Runelords) have female upper bodies and a snake for a lower body.

Quilted Cloth from Advanced Players Guide pg 179. This enhanced form of padded armor has internal layers specifically designed to trap arrows, bolts, darts, shuriken, thrown daggers, and other small ranged piercing weapons. When these kinds of weapons strike you, they tend to become snagged in these layers and fail to harm you. You gain DR 3/— against attacks of this kind. The special layers of the armor have no effect on other kinds of weapons. Effectively DR 3/ Vs Ranged (Bludgeoning or Slashing), or Melee (Bludgeoning, Piercing or Slashing) or Siege projectiles (& Giant's throw rock ability). This can be worn beneath other armor (except for padded)

Other AC Items:

The Neck Guard is made from hardened leather reinforced with a band of metal, this collar protects the wearer against vampire bites when worn around the throat. It provides a +1 armor bonus to AC against vampire bites or similar attacks that specifically target the wearer’s throat. Unlike most armor bonuses, the neck guard’s +1 bonus stacks with the armor bonus of light or medium armor, but it provides no additional bonus when worn with heavy armor.

The armored kilt is made of a thick cloth skirt with bars of steel hanging down from the waist and a ring of horizontal steel plates just above the hem. An armored kilt can be worn separately as light armor, or it can be added to other suits of light or medium armor. Adding an armored kilt increases a suit of armor’s armor bonus by +1, but it adds 15 pounds to the armor, lowers the maximum Dex bonus by 1, and increases the armor’s weight category (from light to medium and from medium to heavy). Adding an armored kilt to heavy armor does not provide an armor bonus increase.
