Burning hands is both a “a thin sheet” and a cone. Which is correct? Is there an easy way to know how to resolve such contradictions? Burning hands is a 15-foot cone. To reconcile the words "sheet" and "cone" in the spell's text, one solution is imagining a waffle cone: a sheet shaped into a cone.

I also like a triangular sheet that rotates around the center line. Et voila, cone.

That is the fantasy equivalent of a gangster rotating their hand to hold their gun sideways. Except it would actually increase effectiveness, but sure. 😂

@tragicjones @mikemearlsIs the bard’s Jack of All Trades feature intended to apply to initiative? PS, congrats on a spectacular launch! Yes, Jack of All Trades can apply to initiative, since that roll is a Dexterity check.

@vamp7777so it would also apply to concentration checks No. Jack of All Trades benefits ability checks, not saving throws. @tragicjones @mikemearls

Hi Jeremy. I see that features from Way of the Sun Soul has different writing on Xanathar's. I know there's an errata for the Sword Coast's version, but it still have different text and "balance".
Should we take the Xanathar's version as the most important one? pic.twitter.com/CteqIIXKtX

Sometimes when we reprint something in D&D, we refine the wording, adding clarifications and whatnot. If those clarifications result in no mechanical change, we often don't include them in an errata document.

In the examples below, the features are functionally identical. #DnD https://t.co/mhl1LlErOF
