Hidden Stage Cleared

I've cleared the hidden stage in 10-10. It wasn't easy since I'm a beginner, but I managed to do it somehow. There are many rewards from various events... I didn't pay attention to them at first and only claimed them later. For those just starting out, I think you'll have an easier time if you carefully collect all the event rewards. It seems like clearing the hidden stage is possible with legendary characters like Sa-hwang or Seven Knights at 6-star level 5 enhancement, and equipment at level 6 enhancement. There's also faction enhancement... that's quite efficient too. There might be many veterans out there, but since even a clumsy beginner like me did it, I'm writing this to encourage you all.. ^^
