什么时候能解决啊

I love this game, and the more I play it, the more I figure out how it works. But I'm stuck on Level 6 and don't know how to get past it. Several times now I've built the best team I can think of and upgraded as much equipment as I could. But the Demon Lord mows my teams down in about 5 seconds. I don't understand what I have to do to conquer 18 Level 5 mobs, including a formidable boss, with a team that only consists of 7 Level 4s and 3 Level 5s. As far as I can tell, I've completed everything I can find...

As above so below

seems pretty dead here, is this game abandoned?

I says "..., and each piece of equipment synthesized permanently gains [5,6,7,8,9,10] * equipment level physical attack" What does this mean? I see no indication on any equipment the Blacksmith is equipped with, nor do I see any additional Physical Attack on the equipment crafted. Furthermore, what good is Physical Attack on a Mage unit's staff/wand/book? it seems even if this ability did the thing it claims, that it would not be very useful for a all pieces of equipment....
