Changing characters

I dont know how to change my team to build up their xp faster or to use to fight.

TIA

If you’re talking about the arena they’re randomly chosen. If you’re just trying to change your team for a dungeon, it’s not explained well but, you need to drag their portraits from the bottom of the screen up to the character you want them to replace.

Thankyou for your swift response
I will try that now

Indeed, changing characters is done in the character menu (4th tab), it is described here: https://ludia.helpshift.com/a/warriors-of-waterdeep/?s=game-information-characters&f=how-do-i-swap-party-members

Thanks for the help peeps
