Nexus Clash

Put simply, there are neat symbols for all the Elder Powers on the wiki - I think it would be cool if you could graffiti them on the walls with chalk, magic marker, or the still warm lifeblood of your foes in order to show your devotion!

There is definitely room to expand on using the symbols in-game. It could go a number of different ways, but allowing players to control their proliferation could make for a fun lore vehicle for characters.

This relates closely to my poster suggestion.

There aren't plans to add images to graffiti. You can always roleplay this with text.
