I like being the attackerdo you want to be the attacker or the supporter?
I'll look at Atwiki for that.
Hmm, well how easy it is to get lvl 7 items probably depends on how many drops you get per fight and of which quality they are.
What I mean is that you only get lvl 7 from 栄光の~(RARE4~7) (for Amulets 歪んだ is that right?) IIRC so you'll need a quest that
A: has that level - the easy monsters don't have that, only
group 1: イャンガルルガ、キリン、ゴア・マガラ、ジンオウガ、ティガレックス、ティガレックス亜種
only lvl 91+
group 2 better: キリン亜種、クシャルダオラ、シャガルマガラ、ジンオウガ亜種、テオ・テスカトル、ブラキディオス、ラージャン
lvl 81+,
B: has many drops
You can see that in the table 報酬枠数
example teo has the most テオ・テスカトル 8~10

For amulets the best method IIRC, once you have an amulet of lvl 7 is to put it into the highest level synthesis/mixer in the last town, that gives you more amulets than what you put in. Save once you put them in and do enough quests (the tutorial quests where you only have to turn in an item) and then look at what you got. if you don't like the result/ didn't get more lvl7 reload without saving and check again.
The more lvl7 you put in the better chance to get more through that.
There was a guide for that I'll see if I can find that again but that's the bottom line.
Looks like I need to rank up that teo
