I've been wondering, in order to prepare for new advanced 5-Star Equipment, should be get our preceding pieces of a certain set to Lv10? Or do we only need to worry about Lv5? For example, does it take a Lv10 Vile Striker (4*) to forge a Deadly Striker (5*), or only Lv5?
Thanks for any information.
I think you should worry more about 5* mats. Those'll come in slower than your equip leveling up to 10? :P
