Class Transfers
The pages are google translated, so it can be off, but I think it's still understandable. Thank you @Shuma for checking the links! <3
2nd class transfer quest step can be saved if you click on the desired row, so you can continue where you left off.
On Eternal 1st and 2nd class transfers are free, when you are the appropriate level (20-40) you can class transfer in towns via Cat or bottom right corner medal icon
On Signature you can donate for 1st and 2nd class quests or do them, the Maria NPC in town is the donation means of transferring class.
