Ray of Frost, Scorching Burst and Phantom Bolt are Dead

[Psikus]

How about splitting the difference and making it 2d4? Give the poor unappreciated d4's something to do now that they aren't needed for Magic Missile anymore.

Oddly, that would be a nerf for some wizards! Enlarge Spell (every pyromancer's favourite feat) has a penalty to damage that scales with number of dice, so that the enlarged Scorching Burst would actually deal less damage under your version.

Upgrading Scorching Burst is easy - just change the damage type on Freezing Burst from cold to fire, scratch out "Freezing" and write in "Scorching," and you're good to go.

I don't have the Red Box, so I don't know what Stoneblood does.

I know that scorching burst is thrashed by other AOE at-wills.

I'm not sure what exactly is beating out ray of frost or phantom bolt in their respective niches?
