How do I use multiple damage type attacks that aren't separate values?

[nytemare3701]

Normally, an attack with multiple damage types is set up as XdY TYPE for each damage type. Quite a few attacks in 3.5 and PF have hybrid damage though, dealing half of their damage as one type, and half as another. Things like divine fire, kineticist's charged blasts, etc.


How do I set up an attack action to deal XdY (Half A, Half B)?

EDIT for clarification. I'm looking for XdY+Mods (Split Evenly between two types), not XdY+(0.5*Mods) + XdY+(0.5*Mods). That would end up with uneven damage dice.

You probably have to handle this very specific case manually. If you don't want to do it that way... you can...
Set it up to roll 1 damage type with the 'Half' modifier applied.. then add a second entry that you can drop the damage in as a bonus with the second type set. This will then apply that specific damage as that type when the damage is rolled.
