The permenantcy spell, as listed on the SRD, requires materials to cast. In this case, diamonds. The spell lists the diamond cost by spell and magic fang is 2,500 gold in diamonds. I'm assuming that this would be in addition to the cost of the scribing. If not, cool beans, I have some lovely gold to spend.<br/><br/>I wonder, does anyone know. If you are crafting your own arrows, could you substitute alchemist fire for the holy water in a raining arrow? The raining arrow acts just like a flask thrown for a splash attack, so it<em>should</em>work the same way, you would just have a fire splash instead of a holy water splash. I don't think that the damage is any different for that matter.<br/><br/>I made a boo-boo on the efficient quiver and got back 1,200 gold when I corrected it. (I had 3,000 gold as the cost when it was only 1,800.)Add in the nearly 2,000 I can scrounge from dropping a little, and I have coin to expand things with.
