How Does Shiny Stone Work?

[Daisu]

Okay, I'm confused, I know it gives health regen when not fighting and standing still, it doesn't work if you have over-time debuff on you, what else?

[Pixel Peeper]

According to the wiki, pretty much everything will disable the regen buff.

I've got to admit I don't see much use for the item. It looks like it's a way to shorten the time spent standing still and waiting until your HP regens, which can take quite a while, but that's kind of lame.

Summon pets do not break the regen, so it's really good for afk farms on expert mode where the normal go-to slime statue does more than 1 dmg.
And with the "nerf" of immunity from spikes (should have seen this one coming tbh, remember meteor/hellstone was the same thing) it's a really really good item for farms.

For general use it's maybe not so great no, but when standing still fishing it's useful, but as you stated any debuff turns it off so farm for that Ankh shield.

remember meteor/hellstone

those were times... but I think I can come up with a better one now, they can't keep nerfing stuff for ever :D
