Is there any way of knowing which tentacle could lead you towards the atrium?
What is an easier way of finding the correct Big Tentacle that would lead you directly to the atrium? One of the worlds I'm in around day 300 I'm looking for big tentacles and I've searched for 8 in game days and couldnt find it with any with a chance, I feel that finding the atrium should not be rng based, having your luck only be based on the world generation. But there at least there should be a better way of detecting it making it easier to track and make it easier then wasting time and fighting one just to get sent to a random/useless area far away from your spawn.
Idea:
Maybe for an idea, having the ancient medallion (which is already used to track the ancient key) could be a way to find the atrium whenever your near a big tentacle, you can scan it with the medallion and the character will pull it out and wave it up and down for a few seconds. (sort of similar to the animation of the map in shipwrecked) When the character is done they will say whether it's right or not, if they gotten the right tentacle maybe the ancient medallion will drop out their inventory, float up in the air (animation similar to the celestial orb) , and start shaking while pulsing out nightmare fuel(not collectible just for detail) for a few seconds.(for example Wilson would probably say something like "Yup, that's suspiciously a lot of magic for a slimy pit." if the player gets it wrong they'll just assume there's no magic anywhere (another example wilson probably simply just saying "Guess it's just a dud".
