Beads of this Blackish-green slimy gray oil form on the outside of its container, stinky and disgusting but quickly evaporate. The oil can cover a Medium or smaller Armor or shield (one additional vial is required for each size category above Medium). Applying the oil takes an entire turne in combat or a moment out of combat. The affected armore have +1 AC for 24 houres (this effect is expanded 24 hours if the armore is not used in combat within the last remaining 24 hours). In consumes, the target must roll a dc 16 con save. On a failed save the creature takes 4 con damage and is poisoned. On a succes 2 con damage but still poisoned. The poison last for 12 hours and grants the creature immunity to poison as long as they are posioned and have the con damage from the oil. "Also drinking an oil is really stupid" - Zitch Longpaw
