We'll have to talk a bit about help actions as well. I want to tighten up how we use it. In Lunitar's game, we are pretty guilty of using it as an
improved guidance cantrip that anyone can cast. We've trivialized more than a few skill checks in that game, and at least in my case there were times where the described assistance was pretty flimsy.
The link article sums up how I intend to adjudicate the help action in this game. Anybody is welcome to state their character is 'helping' another character and describe that assistance, and to save time the helped character's player is welcome to roll with advantage. You can even say you're helping after the roll was made to retroactively add advantage, such is PbP. However, I may rule that help as described was not sufficient to warrant advantage, and use only the first d20 roll to determine the success or failure of the check if you've already rolled it.
As the linked article describes, helping a character with a dangerous task opens a up the helper to the same dangers, or it may require a skill check to perform the helping action.
Generally in combat I'll be happy to let the help action stand, although a bit of role play as to how you're helping is still required.
