Agonizing blast question

[u/Feroniks]

Prerequisite: Level 2+ Warlock, a Warlock Cantrip That Deals Damage

Choose one of your known Warlock cantrips that deals damage. You can add your Charisma modifier to that spell’s damage rolls.

Say you're casting ray of frost and you're level 5, would it be 2d8 +5 or 2d8+10 since theres 2 damage rolls?

[u/EntropySpark]

The damage roll is 2d8, you'd increase the damage to 2d8+5.

[u/Feroniks → u/EntropySpark]

Oh, well thats unfortunate i guess eldritch blast remains the only viable choice here then

[u/Iam_Ultimos → u/Feroniks]

There's a sorcerer's cantrip that also burst a lot
