Listing the possible results of saves and fails for this situation is helpful, thanks! I also appreciate your other example of a boulder down a hallway because I wouldn't know how to word it if someone does succeed a DEX save. I could say there was a hole in the ground and they happen to fit in...
Thanks for the super fast responses! I didn't know people reply so quickly so I really appreciate it. I'm kinda new to this forum so I'll try to keep up with it.
I'm playing a dragonborn Monk so I'm able to carry a person/other Players bridle-style. Since I have "Evasion" and when I succeed I take no damage from, for example, a Fireball, does the person I'm carrying also take no damage?
