I was watching a YouTube channel that does P2E builds this morning. This one was for a grappler-type character, and it mentioned taking Assurance to avoid the Multiple Attack Penalty.
That seems like a total hack, so my first instinct is that it can't possibly be Rules as Intended, and probably a misreading of RAW as well.
But going and checking the current wording of Assurance, I see this (emphasis mine):
Choose a skill you’re trained in. You can forgo rolling a skill check for that skill to instead receive a result of 10 + your proficiency bonus (do not apply any other bonuses, penalties, or modifiers).
So assuming Multiple Attack Penalty is a penalty like it says, then it looks like Assurance means you have the option of ignoring it for athletic skill checks that count as attacks.
Am I missing something here?
