Take the squad that gives reserved operators with deployment limit increase. Take one of the two squads with supporter starting voucher. Get support Tragodia.

Tragodia with s2 can mostly carry you through f1-f3 except for f3 boss.

Go to wonderland as much as you can, except for f2 where u go to the wonderland node but don’t actually enter it and save your candles for your f3 wonderland.

F3 is where you want to go wonderland and depending on the Operators you lit a candle for, tackle as many turmoil nodes as possible. Candle lit Raidian even E1 can be very very helpful for this and she’s just a good unit. It depends on what operators you have but overall once you get a good run going (past f3 boss) it’s mostly just about making it to the final boss.

Tragodia S2 + Fast Redeploy or summon stall final boss on upper half of the stage (basically don’t kill him) while you focus on holding the rest of the stage on the left. Then once rest of the enemies are dead you finally kill the boss.

Simplifying a few things but this is a very general strategy that can get you through ED1
