Breath weapon and sneak attack

[Maester Jun Ixnar]

Question: Can a character gain precision-based damage with a breath weapon (a supernatural ability,) spell, or spell-like ability, assuming that all other requirements for sneak attacks are met?

[Claxon]

No. Breath weapons do not have an attack roll. Sneak attack requires you to make an attack that involves an attack roll. Which is why you can't sneak attack with a fireball unless you are a 10th level arcane trickster.

[Avoron]

Claxon, you are correct, but I believe you may have misinterpreted the phrasing of his question.

No, you cannot sneak attack with a breath weapon that does not require an attack roll.

However, you can sneak attack with supernatural abilities, spells, and spell-like abilities that do have attack rolls.

Claxon and Avoron answered the question; thank you much!

[Claxon]

Yes, if an attack has an attack roll, and you meet the other requirements for sneak attack then you can sneak attack.
