Priest spells, third level--components

Priest spells, third level:

• Animate dead (E): The other material components listed are not as hard to get as the corpse being animated; you can probably extract the blood, flesh, and bone from the corpse
• Flame walk (C): 500 gp powdered ruby
• Glyph of warding (C): Incense (1 gp): also, if area is larger than 50 sq. feet, needs an additional 2000 gp powdered diamond (!)
• Locate object (C): lodestone (1 gp)
• Prayer (E): Seems to require a better-than-usual holy symbol, but anything used for augury should more than cover (I think it’s implied the component is not expended when the spell is cast)
• Speak with Dead (C): Incense (1 gp)
• Stone shape (*): As a house rule, stone shape has no material component
• Water walk (Q): Cork
