This is not a low rarity guide or F2P guide for today. (Might be one later)
It is just one of the strats you could do.
Chen just need to be E2 with SLv7 or above
You really need high healing aoe medic like Ptilopsis / Nightingale or Perfurmer with E2 at least
Sorry for today daily as I wanted to attemp Risk 24 caster team asap so I have less time doing guide runs. Hope you guys dont mind and have fun with new risks !
