I don't suppose the rules for refunded equipment also applies to copied spells, huh?
I have a Rogue/Alchemist (Vivisecionist) who is going to have to be reworked now, but I've already invested a bit in copying spells found during scenarios into his formulae book. The main draw to Vivisectionist for me, admittedly, was the Sneak Attack progression, and although I've grown to appreciate other aspects of the Alchemist Ive been ruminating on dropping it entirely due to this change. However, if changing classes means losing the gold spent on adding formulae to his book, I may have to give the decision more thought.
