I'm going to assume you're on a Seulbi. Please tell me if you aren't, because these are magical character equips.
Like Ace said, make the 3/3 from Plane Gate. It shouldn't take too much to craft, but if you don't have enough Red Orbs, just go back to Epilogue and craft both magic sets and 1 of the hybrid sets:
For the hybrids, the set at the top gives additional Aerial Damage and the one on the bottom gives Chase...up to you. (Aerial easier tho)
For endgame, if you're magic class, then you're should to be working towards getting the highest possible version of the Dark Blue and Yellow legendary shields. Whether you want the no-set or the set is up to you.
Just get 3 of these (the one highlighted in yellow) and +7/8 them:
For endgame, if you're magic class, then you're should to be working towards getting the highest possible version of the Dark Blue and Yellow legendary magic modules. Whether you want the no-set or the set is up to you.
(They look like this:
What endgame said.
I would just +8 it because you should be crafting the elite lv52/53/54 Epilogue Weapon after that one (until you get the legendary for yourself, ofc):
While attempting to craft to the lv54 version, do not enhance the lv52 one, because it's pretty much the same as the lv52 Epilogue Weapon.
Also, get used to that lv52/53/54 weapon, because you're going to be stuck with it while trying to get the legendary weapon you want.
Speaking of which, in response to what death said:
Those are the boxes you'll be opening for your weapon. First one is for Physical, second is for magical, and third is for Yuri.
The boxes can be found on 8th tab of plane gate crafting
Also, unfortunately, inven is out-of-date when it comes to stats (due to lv cap raise). So you're going to have to check stats in-game.
It's also good to note that naddic adjusted many sets to have critical rate stats be the first set rather than the last, so using the set equips is a more viable option now.
