[@Vec] I see, well to keep it simple if another divine being choses their domain to be Wisdom of Wisdom, Knowledge, or Strategy then Adria's domain ends with battlefield decisions. I figure she wouldn't hang around the tent all day when she could watch over the battlefield. 

As for appearing before dying soldiers, I was actually thinking she's just there to comfort them in their dying moments. Similar to Hermes in that regard. Where she offers them kind words, making them feel pride and unafraid of death and when they die, she guides them to death's domain. It's similar to what you said about overlapping the gods' domains, and I was just trying to restrain myself a little. But if you want her to take on the quasi-ferryman role until a death god shows up, she could be that too. If you want or need it to be so.
