Octopath CotC | Kagemune EX3 5T | ft. Rainbow team (without LynetteEX)

No LynetteEX? No problem :D jokes aside in absence of Lynette EX there are a few options: the main point is getting 15% e.atk and e.dmg active buffs and as many other (missing) buffs as possible. In this case I choose OsvaldEX due to his ability to transfer 20% of his e.def to e.atk to front row, a useful nuke that caps without investment, and the needed shieldshaving. But I also did runs on other bosses with: Bargello (active + passive buffs, dmg cap up) Agnea (Extend the active buff cap, buffs like a queen, a little bit of dmg cap up) CasstiEX (active + passive buffs + FUA, decent damage) Rinyuu (Just set her atk buff on and forget about her) I'd try also RinyuuEX and a few others that I didn't had a chance to pull, simply think in terms of missing buffs and "turn investment / placement"
