I agree with everything except fool. Fool was fine before the patch, there was no reason to change it.
Agreed, the only changes that sellsword needs are giving her a one-time night immunity and changing it so she needs to survive. I get why faction members don’t have to survive as they have an entire faction supporting them, but Sellsword is on her own. And maybe giving her bewilder as a day ability. That’s it.
And changing the win condition since it’s easy.
I like the idea, but it wouldn’t fit sellsword’s theme. Maybe a separate neutral offensive class could be added which is based off of the Witch in ToS.
