Maybe a d6 roll, with the 6th die roll affecting that creature twice with two different types of energy? Same damage, just that half of it is one element and the other half is the other element.

And I got traps, yay. You can start the character generation now, 3.5 SRD rules, without any of the 'splat' books. Those books with the additional material seem to tend to be unbalanced, and allow you to powergame too much.

EDIT: Hehe, forgot the rules. 32 point buy, level 5, you can use psionics if you want...
