So..wow, didn't know Domain Invasion was so easy. I guess I found something to kill time with until I get those two drops I like.
Correction..was easy until idiots started spamming Spike Flail.
For COR on those, I usually used Arciela I, Sylvie (unless real people were there, then I guess another healer or somehing), Iroha II, Selh'teus, and Nashmeira II. Tanking in the back is actually easier this way as Absolute Terror just lasts way too long. The trusts will keep healing regularly; Selh'teus' aoe heal gives MP and 500 TP too, so Arciela and Iroha will likely be ready if they weren't. Nashmeira II has Curaga V and her only WS resets her hate. Only major concerns are if Azi Dahaka flails with Mighty Strikes up, or if Quetzalcoatl uses the sleep move too much for trusts to stay awake.
Use Rogue's Roll and spam Evis, as each critical hit you land is worth 100 points, so it builds up very quickly to give you a capped evaluation. Higher eval will give you more CP, silt, beads (in case you want to ever make Fomalhaut), and greater personal loot, including money items.
