Hey Aaron W. ! You should be able to set the damage types of NPC and PC attacks when editing them individually. As a note on NPC sheets - if this is what you're referring to - attacks only have one field for damage if you're adding or editing them by clicking the Edit button at the top, or editing in Stat Block view. If you'd like to give an attack a second damage type, you'll want to add / edit that in Compact view rather than Stat Block (you can change view in the Settings at the top). Then, you should be able to see two damage fields by default when you click an attack's edit icon, and add as many damage types as you want in the advanced edit modal. Many edit tools are more powerful in Compact mode, and left out of Stat Block's inline edit for space - but if you set the attack up in Compact view, then toggle back to Stat Block to actually use the NPC, it should roll all the damage types you added.
