Fire is not a potion effect, so I find this unlikely.Same goes for several other pendants when ur in the Nether (effects reverse) Example: fire resistance lights u on fire in the Nether, but since timer is 0:00, u dont receive any fire damage.
I also find this unlikely, though not problematic if true.There's a bug where wearing pendants of any kind will transmit ALL crystal related buffs. Say I wear a brown pendant for saturation and I am just sitting by a pink crystal? The moment I hit something they get STRENGTH! Even tho I have no pink pendant! I just happened to go by a pink crystal!
Items are ticked in slot order; hotbar is 0-8, and the rest of the inventory is 9-17, 18-26, and 27-35 respectively.Also: The white pendant clears all other pendants if it's to the right of them in teh inventory, but doesn't clean the other pendants if it's to the left. I guess that's how the inventory works...
