CRB, page 580: "The DC of the Crafting check to transfer a rune isdetermined by the item level of the rune being transferred,and the Price of the transfer is 10% of the rune’s Price,unless transferring from a runestone, which is free. If you’reswapping, use the higher level and higher Price between thetwo runes to determine these values. It takes 1 day (insteadof the 4 days usually needed to Craft) to transfer a rune orswap a pair of runes, and you can continue to work overadditional days to get a discount, as usual with Craft."
Do i need to be expert to transfer runes, that require "expert" to craft it ? (Text says only to take DC)
Do i need to have craft magical item feat to transfer runes ? (This is important, because transfer rune isn't crafting magical item. And i compare it with battle medecine which isn't treat wounds and doesn't require healing tools)
What is total cost to transfer rune? (you can continue to work overadditional days to get a discount, as usual with Craft.) Is it 10% first day and i can get 90% discount? How does it works with runestone? 1 day is for free and i can get 90% discount?
