Bladeguard

Source Advanced Player’s Guide

This clear resin protects a weapon from harmful attacks from oozes, rust monsters, and similar effects that corrode or melt weapons, rendering the weapon immune for 24 hours. One pot can coat one two-handed weapon, two one-handed or light weapons, or 50 ammunition items. Applying it takes 1 full round. Immersing the weapon in water or similar liquid washes it off.

Alchemical Power Components

 Source Adventurer’s Armory Weapons and armor aren’t the only things bladeguard protects.

Wall of Iron (M): For each pot of bladeguard used as a power component, you may designate one 10-foot square of iron wall that has acid resistance 10 and immunity to rusting attacks.

An alchemical power component is an alchemical item used as a material component or focus for a spell in order to alter or augment the spell’s normal effects. What follows is a sample of these effects using this item as a component; your GM may allow other combinations.

_{Spells followed by an (M) expend the alchemical item as a material component;}

_{Spells followed by an (F) use the item as a focus and do not expend it.}

In both cases, the alchemical item does not have its normal effect and does not affect any other parameters of the spell. You cannot use the same item as both a focus and a material component at the same time.
