The Challenger Idol is a mysterious and ancient device locked deep underground by a magical seal within the Trial Chambers. If unleashed, a dangerous curse will seep through the land, granting great power to hostile mobs in a 1000 block radius.
There are a lot of changes made while under the effects of the Challenger Idol, listed below:
Zombies and Skeletons will frequently spawn with full gold, iron, and diamond armor, with one piece being trimmed with one of four unique patterns with Obsidian called "Tainted Armor" harboring powerful Enchantments, and one guaranteed curse
Alongside rarely their trimmed armor piece, these mobs will drop tons of Bottles o' Experience
Wither Skeletons will only spawn rarely with Netherite armor trimmed with gold, which have a chance of dropping a Netherite Upgrade Smithing Template
Various mobs may now spawn with positive effects, such as a couple of the Ominous Trial effects, as well as Speed and Strength
Spiders may place multiple webs when webbing, and are immune to fall damage
Endermen are notably faster
Drowned may spawn on land during rain
During thunder storms, they also have a higher chance of spawning with a Trident, which may have the Channeling Enchantment
Charged Creepers will occasionally spawn on their own during thunder storms
A new deadly encounter will occur... The details of which are for you to discover :)
