I think there is a parent attribute that works for both. It might be initiative_bonus, I'd have to play around to be certain. I know for a fact that the Community Contributed 5e sheet has separate attributes and if that is the case for 5e OGL, you can use the same technique to deal with it: Add an attribute manually to each PC with a value of 0. The name is not important, only that it doesn't clash with something on the character sheet. I use pcinit. Add a rule that adds that attribute and the attribute for PCs. !group-init --add-group --Bare initiative_bonus --Bare pcinit Add a rule that uses just the NPC attribute: !group-init --add-group --Bare npc_dex_mod In so doing, you create a rule that will only match the PCs first (because pcinit will only be defined for them), and npcs second. I don't think this is required for the OGL, but if it is, that's how you do it.
