Other than status themes, the addition of night on levels randomly.
At the gate, an NPC knight[most likely a recon knight] stands next to a locker filled with recon-light packs that are auto-added to a knight that passes through. Every knight is individually lit with a circle of light.
Different from Candlestick Keep in that light in constant, though the darkness is pitch black until you have explored it.
This can bring a more lively feel to levels, and prompt new night-based creatures/themes that arn't seen in the daytime, as well as special loot/room designs to reward exploration.
This also makes more obvious use of the toggle map that was recently added.
This might have been suggested before at some point, but not sure. Please give your thoughts!
A neat concept, but it'd just encourage people to farm KoA even more because the night will slow them down.
