chromatic orb and conjure minor elementals

does the damage enhancement from conjure minor elementals count as rolling "doubles" for the purposes of chromatic orb being able to leap to another target?

conjure minor elementals says "any attack you make deals an extra 2d8 damage when you hit a creature in the emanation"

chromatic orb says "if you roll the same number on two or more of the d8's, the orb leaps to a different target...."

assume both spells are doing the same damage type. 

I'd say that "... the same number on two or more of the d8s" refers specifically to the 3d8 damage rolled for the spell, not including any extra damage from other sources.

EDIT: 3d8, or: "Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 1."

I agree with this interpretation, especially since CME was nerfed to not scale by 2d8 on upcast. D&D is supposed to have strong combos otherwise everything becomes homogenous. casters are already punished in this edition with concentration. Johnny Combo player plays casters for stuff like this and is sick of the fun police tying to find a way to take away what is not ambiguous wording because they want to argue about RAI. no combo is RAI, that's part of the fun. when you cut that out you cut out an entire demographic of players. it's not that broken honestly anyway.

"the d8s" definitely refers to the d8s that are only the result of Chromatic Orb.

As for "it's not that broken anyway"... A non-upcast CME means a 5th-level CO guarantees bounces under this interpretation. That's huge.

I agree that the spell is referring to the d8 from the spell itself, and not any outside added damage.

Like, if you have a +2 to the spell always, and then roll a 2, you wouldn't make it bounce, you know what I mean?
It adds damage to the spell but doesn't affect the chance, because that could make it way more likely for every d8 you add.

But you don't have to adhere to the rules; you could always either homebrew/use houserules if you (and/or your DM/players) find this interpretation more fun.
Wizards of the Coast just gave you the base rules so you can have fun. Play DND however you like
