Yes it is safe. They let you test out SS and GM 3rd tree skills with the loli sister. like Ping pong EX Mecha duck EX, Big flying duck (That is what i call one of the GM skill)
You will only complete your quest for class change only at Lotus Marsh and after talking to the vase/jar.
You can only choose one job. either SS or GM. but since Engineer can only choose either one of them for the 3rd class.
also if i not wrong. SS class is the alfredo tree and GM is tower + duck tree.
depending on what skills you set in your engineer.
IF you still have lvl 15 job change skill reset scroll with irine, you can reset yr skills.
I did a SS tree line with my loli but realised that duck + tower tree suits my play style more.
If you still have doubts with it. let me know and i will help you tonight +8GMT time. around erm 2000-2100hours.
