# Can Lucky be used on an attack roll if the roll is a 'Nat 1'? [duplicate]

Rolling a 1 or 20, PHB pg 194

[...] If the d20 roll for an attack is a 1, the attack misses regardless of any modifiers or the target's AC.

Lucky Feat, PHB pg 167

[...]You can choose to spend one of your luck points after you roll the die, but before the outcome is determined.

Rolling a 1 on an attack roll (Nat 1) is often called being an auto-fail and with a good reason. Is it intended for these rolls to be instant failure/success? Because as soon as you see that 1 on the die you know: you have failed and there is a limited number of ways to change that. The question is: "Is Lucky one of them?".

I can see a DM calling "You have failed so hard that even your inexplicable luck can't get you out of this one", and it is usually fun for the players when something so unlucky happens to someone else. At least in my experience. My question is if it was meant to be like that as seeing that 1 alone can be a confirmation for failure. Are features like Lucky(dice manipulation features) worded that way to prevent these manipulations?

• Is ther anything about the wording of either that makes you think you can't? – Jason_c_o May 29 '18 at 14:26
• @Jason_c_o Yes, my thought was as rolling 1 or 20 on attack rolls are always failures or successes, you'd know the outcome so you shouldn't be able to use Lucky. Of course after reading the answers i realise that's not how it is. – FenrirG May 29 '18 at 14:29
• @FenrirG I don't think that lacking a quote in an answer is enough to distinguish the questions. The linked question seems to be more generic and already including your case. Maybe the answers there could be improved with the quote though. – Sdjz May 29 '18 at 14:34
