It's not my guide. I found it on youtube and thought it may be useful to post here since there is no guide here for this latest raid.
Notice they recommend +9 weapon. That's because it's much easier to upgrade your gear in other regions. (Somebody in the comment section said it takes them around 35 attempts to get +8.)
In our version, many groups are currently looking for +8 for manic runs, but I'm pretty sure those requirements will go down once more people are familiar with the raid.
