Do I have scorching ray right?

[Ched Greyfell]

This will seem like a stupid question. Since, I can sit here and read the rules right out of the book. But... just making sure.

If I use only one action. It does 2d6 fire.
But if I use 3 action to fire at 3 targets, the damage per target also increases, doing 4d6 to two or three different targets.

So, a heightened 4th level scorching ray would do 4d6 to one target. Or 8d6 to three different targets? Do I have that right?

Yep, you have that right.

I would point out, to ensure full clarity, you can spend 2 actions to cast scorching ray to target two targets at the higher damage level.
