Whelp, I did it! After like a hour of save loading and fine tuning! Cid mission ffx party complete. Honestly the two major orbs you get for this are not worth the trouble, but if you have nothing better to do its a neat challenge I guess.
This was my squad,
I decided to blow my orbs on the power chain/ full charge so Tidus could be useful. Sure as hell couldnt have accomplished this without it! I mean, damn thats actually a really powerful combo for a char that I have no Soul Break for.
Yuna would heal but I tried to get as many Diagas in as I could as they were doing around 8300 in damage. Definitely helped me succeed.
Auron spammed his SSB as much as possible and it did wonders. Very thankful I have this thing.
Rikku would Power steal on occasion and I
tried to Dismissal spam. Only worked twice on my successful run but I'm sure it helped. I totally forgot I had her SB that is like a weaker boostga, but I didnt use it because I didnt want to overwrite shout.
Wakka I gave my knife that has a shared Soul Break of Protectga on it. THen I'd just full break and armor breakdown the boss till the end. He was the only one who died but he did his job.
I didn't lose a single medal somehow. I was quite surprised. I cant say I'll be able to complete future Cid missions, I honestly feel like only the whales will complete them all. But I feel like thats what the cid missions are for. This was the first Ultimate in like half a year I didn't use a Wall relic for. I forgot these things were even possible without them.
