Weapons & Equip Make the shellaphone give bonus readouts:

[RainbowPotato]

The shellaphone would have a limit to the amount of readouts, but you can always swap. Some examples would be;
Examples:
- Total Distance walked (feet)
- Total Items Crafted
- World Corruption meter (replaces dryad but you have to work so hard to get it, i think its fine on this list)
- Distance from closest chest (specifiable)
- Rare item dropped detection
- Chance of rain
- Current Regeneration rate
- Average Happiness meter (within 100 blocks, says undefined or error if none nearby)
- etc, i will let more be suggested in the comments, while some comments can improve some others or elaborate.

Hard disagree on the "add ons". The shellphone is already an OP item everyone is going to have anyways, does it really need to be even more OP?

That being said, I do love the functionality, but feel a separate accessory would probably be the best way to go about this. I made a post on it you might like: Weapons & Equip - Thermal/Spelunker Vision Goggles, but note that as an accessory, there is actually a trade off you need to make as opposed to getting this for free simply by, again, having an item in your inventory that you were going to have there anwyays.

What if it was locked behind mechs with chlorophyte being required to craft it? Idk, still really OP.

Hmm would be cool if certain utility buffs like the spelunker or hunter being a charm attached to the phone when you combine it with the phone hunter would be a like a bright Eye dangersense is a Excalmation point
And spelunker would be. Yellow pickaxe
