@JeremyECrawford If I make 1 attack with a longsword as a part of casting Green Flame Blade, while having the Hex spell affecting the target, and then I use Divine Smite once the attack hits, how many damage rolls are there?

When something in the game (Sneak Attack, Divine Smite, hex, etc.) causes your attack/spell/etc. to deal extra dice of damage, those dice are added to the damage the effect is already dealing, if any. It's one big damage roll, extra damage included. #DnD https://t.co/eWZ6dsefEl

Would only be a second damage roll if there was something locked behind a save like poison damage, yes?

If an attack has a damage roll but also a second damage roll (not extra damage) that is contingent on a saving throw, the damage of that second source is a different damage roll from the first. #DnD https://t.co/7amoNNvsKD

So Hex on a net is added to the damage already dealt by the net aka zero?

The hex spell doesn't require an attack to deal damage for the spell to work (0 + 1d6 = 1d6). The spell requires the attack to hit. #DnD https://t.co/axAZ1RX9Cp

how do you distinguish between second damage roll and extra damage?
— Nathaniel Mosher (@RubiksMoose) March 23, 2018
Separate damage rolls are delivered by separate attack rolls, saving throws, or other processes. Extra/bonus/additional damage is called extra/bonus/additional damage. #DnD https://t.co/1XIfKsYHo4

Is that additional damage impacted by a critical hit?
— Meat Voltron (@Preacher23) March 23, 2018
Saving throws can't score critical hits. If a saving throw is contingent on an attack hitting, the save is unaffected by that attack scoring a critical hit. #DnD https://t.co/cMaEBP5tyK
