If a Wiz uses Portent to replace a PCs save and the PC uses Lucky on his save roll, which roll would overrule the other?i'd use lucky first, then apply portent; or if lucky not used and portent is a 1, use portent then apply lucky

Ah, missed that restriction on portent. So, apply portent, then if a 1 you can use lucky.
