Ok, I know Eschew Materials feat allows you to cast spells with up to 1gp worth of components without the actual components. I thought I had read something somewhere that replaced a larger amount, but I cannot for the life of me remember if it was a feat, item or even whether it was part of pathfinder or somewhere in 3.5...does anyone else remember this and know where to find it, if it even exists?
There is a feat in Inner Sea Magic called False Focus that allows to have a divine focus to replace any material component up to 100gp (I think). You have to buy a focus worth 100gp to make that possible, and it only works for arcane spells.
it only works for arcane spells
Actually, you only need to be able to cast Arcane spells to take the feat (and have a skillpoint in Knowledge(religion)). It should work just fine on any spell you cast - so if you can cast the two kinds of spells, you could use your real Divine Focus as a "false" one.
Thank you :)
