I'm running Hoard of the Dragon Queen and the party has opted to travel as merchants instead of joining the party as guards. Since I was stressing that they were noticing that
the one wagon they knew belonged to the cultists wasn't accepting riders,
… I had Green Imsa try to obtain passage with them. I was not expecting them to take her on and I definitely wasn't expecting the wizard to hit her with Dispel Magic.
Since I was short on planning time prior to the session I hadn't fleshed out Green Imsa a lot. I figured I could just have her evade questions about what happened to her as is supplied in the adventure and then figure out what happened later.
Are there any spells 4th levelmagical effects (or if its a spell, it must be 4th level or higher) that can turn characters green?
