[Granblue Fantasy: Relink] Pageant of Might and Magic - with Katalina

Just came back to the game. I haven't play 1.3.2 yet (Not even get Sandalphon).
This quest is a long fight, so I decide to use only Gamma and remove Stout Heart because the enemies levels are higher than previous version which can't face tank. However, Katalina got minor buff to get the gauge, I think it is still working fine to stop the combo (better than death). and the damage still higher than Zeta bot (245k while Zeta is 226k).
Room of improvements:
Linked Time: I found that bots may focus on different monsters which sometime far from each other and it cause Linked Time can't activate. It is a lot of DPS loss for Katalina since her damage come from Enchanted Lands.
Change Sup V+ to new Berserker Echo+. It will boost quite damage since I only has 1 Suv V+ sigil in the build.
Change Aegis to Greater Aegis. HP will close to 45k cap and reduce risk from 1 shot death.
Note:
I try to play with Tweyen too, she is more safer but less DPS than Zeta bot (162k while Zeta is 194k DPS - 29%/34%). Zeta bot is my baseline LOL.
This run played so bad during earth dragon. But others are pretty good.
