So, the ability to spread rabies by attacking other players with a rabies-infected king exists, but I think it might also be a good addition to be able to attack a rabid king with a non-infected king in order to obtain rabies.

Ideally I'd like to get rabies as close to the time I roll over as I can, but not a lot of folks are able (or willing) to spend 20% energy to attack me and give me rabies. And enemies in explore are awfully stingy when I want rabies, so I often don't end up obtaining it for the day until over 6 hours have passed even with roasted lambs applied.

If players could attack rabid kings to get rabies (if desired) it would mean players with it no longer feel any pressure to attack others who want it, and it would be easier for those players to obtain it without having to wait for a player to attack them or hope to get it early from explore battles. All it would cost is 20% energy if they want to spend it.
