Okay it's late, but I'll do my best to explain. This is something that should apply to all God Slayers in the rp. *is super tired*

You know how Dragon Slayers are able to consume another element and then use both elements for a temporary time that gives a power boost similar to Dragon Force (Example: Natsu (Lightning and Fire) Gajeel (Shadow and Iron)? I think God Slayers should also have that ability to eat another element so they can enter a duel elemental state as well. It make sense both of these slaying magics have both mages consuming elements and to me it doesn't make much sense why a God Slayer wouldn't be able to do that. 

As well as that perhaps God Slayers can also get something similar to Dragon Force. It would be their ultimate state that a God Slayer can reach for that temporary time if certain conditions are met in order to achieve it. What the conditions could be is probably like something that involves consuming substances with latent magical properties or absorbing something. 

I hope that I'm not sounding too much like a jerk.

I just realized today that, yes the dragon slayers consumed another element to gain their dual elemental state. But they only gained their dual state only by consuming not from just any element, but from the same element of another slayer (Ex: Natsu consumed Laxus's lighting and Gajeel consumed Rouge's shadow) all who were dragon slayers. So again, it does seem possible for a god slayer to gain a dual state, but it would have to come from another god slayer's element. The only other god slayers that I'm aware of so far in the RP are Janice who has lightning and Lazarus who has light (I think).

My knowledge usually comes from just the anime and not manga, so I don't know if the manga discussed about the possibility of it.
