The Unearthed Arcana Phoenix Bloodline Sorcerer can use a bonus action and trigger their ability for 1 minute, which reads:
Mantle of Flame
[[.. snipped text..]]
- Whenever you roll fire damage on your turn, the roll gains a bonus to equal to your Charisma modifier.
Does this mean that, under this effect, a Scorching Ray deals 2d6+5 damage per beam (assuming 20 CHA)?
I specifically have in mind the other similar features in the game, the Draconic Sorcerer ability and the Evoker Wizard abilities, which allow their spellcasting mod to be added to damage as well. Also similar is the Warlock's Agonizing Blast invocation.
