Picked back the game and trying to continue the story. But Sunday boss is kicking my ass (Sunday boss when you play Sunday story line, not the original Sunday boss I mean).

I don't have any fire, imaginary or electric dps built. First phase is fine but second phase seems impossible since he just keeps spamming shields one time and another and another. And unlike the weekly version of the boss this one doesn't have the train to help you to break the shield

I tried different teams with Archer, Jingliu and Boothill + SW since those are the only dps I have built but on the second phase once it start spamming shields I'm fucked

What the fuck I do? I rather not turn it to easy to not lose interest. I want it to be a bit challenging to keep the interest, but not THAT challenging
