I wonder, if in the 2da, instead of giving the cleric a different level, why not simply create a copy of the spell Which could be renamed for example Greater Holy weapons, take out all other classes that are not cleric and leave it at level 4. And in the GMW take out the class of cleric. This way 1 now any one else who can cast GMW would be able to take eschew 1 and it cover GMW, and A cleric would have to take eschew 2 to cover GHW?
