That's what I found the best way after few tries yesterday. This one indeed pretty tough compared to other stages later on 😂 For my method: I built team swords on left side (I upgrade it on first round) while team rifles on right side. By the time 10 team rifle reach before the portal, my team swords got enough 20 soldier and both can move to portal at the same time. Just make sure team swords move to portal 1st and team rifle 2nd, so team rifle can stand before them and handle 1st enemies. Beat the boss at Round 11. For my team 1. I let them clear whole 2nd row of bushes and walk around. At least they have some times to kill 😂😂
Your movements are more economical, because the way I did mine does feel like it wasted 1 or 2 turns, while waiting for the sword team to rack up some more units, before heading out. and LOL on your team 1 xD
Feedback : Mention Sohee party will be the boss killer not party 1, I did clear with a single unit thanks to army buff but when you don't mention anything I expect party 1 to be the boss killer
You can deff do this all in 1 go. Use only swords to battle the rifles. Use team one to slowly move forward and beat the boss :) then the other 2 can get the chests
