Evertale stuck on beating tower act 1

Trying to beat swordsman in tower in act 1 of campaign

Level up your Shana, she’s your best character

Where should I put her in my lineup

Shanna goes right next to Miriel (the angel to her right). Finn should be last in your lineup. Catch and use the grey wolf guy who has vigor impact/desperate strike. Level that and the shockling to at least 30-35

What should I deal with my super rare and super super rare weapons

Like this for my lineup

How do I beat this
