Sh’kee, my grung tempest cleric, just used calm emotions to soothe a treant that was starting to become hostile after her group was trying to peacefully get past it to go back up in the elevator lol. She spent like 20 minutes prior to this talking to the treant and asking yes or no questions to discern if they were a ) hostile and going to harm her, b ) happy or content, c ) being commanded . . . after climbing a building, leaping 45+ ft, going through a window, and using a fantasy elevator to get to the lobby where it was sitting in the fountain.
After this though, she and her party got stuck in the elevator and these hostile vines were chasing up ( not related to the treant ) and she used thunderwave . . . which hit every single one of her party members, and all the vines too, but all her party failed and took damage lols. My friends are not pleased but oh well.
