Does this mean D&D Beyond will also have its content updated and added to? Kind of confused. Are you saying the Eberron stuff released on dndbeyond is still considered UA right now? Or that is just doesn’t have all the material yet? We will be adding more material to the PDF, and if playtesting calls for updates to mechanics we will also update the PDF with them Will the version I just purchased via D&D Beyond also receive updates such as the Artificer when the time comes?

then if your speed is reduced to "0" by sentinel feat, dash action will give you "0", not your original speed, that's correct? @mikemearls @JeremyECrawford

That’s correct.

Here's a handy tool for D&D DMs – Want to add a special attack to a creature? Convert a single target attack into one by cutting the damage in half. Turns single attacks into multiattacks or one target spells into area of effects.

Using the stock ogre as an example – give it a big flail that can also do an area attack by keeping that attack bonus the same, extending the targets to everything within 10 feet, and using 1d8+2 for the attack's damage.

If you want to get fancy, you can also do half damage if the attack roll is above a certain threshold, regardless of AC, to make it kind of saving throw-like
