Item Idea: Iron / Copper / Stone compass

As of right now you just search into the blue to find Boss citadels. Even when you find them, it still takes a decent amount of maps to get to it. So my idea is as follows:

Iron/Copper/Stone Compass: reveals a path towards the closest corresponding citadel. It Highlights a path of maps with a trail towards a citadel.

Since you still have to run a lot of maps to get to it, i think its not too game breaking or too egrigious. You can make it drop fairly rare even if you want to but i think this would be a nice addition to the game.

I have 2 characters on lvl 90 and ran hundreds of maps and i found a single citadel as of right now myself.
