Searing Touch
Type: Chestplate (+ other armour on anvil)

Some chests already had the chance to contain randomly enchanted books, so the new entries above are in addition to existing entries of enchanted books in their loot tables. 

• Enchantments generating in loot can be toggled in the config file
• Enchantments appearing in trades can be toggled in the config file (use Enchantment Control to control this in 1.15 and older)
• Enchantments can be set as treasure enchantments in the config file, preventing them from appearing in the enchantment table
• All loot modifiers can be configured using a datapack
• If you have Quark Oddities installed and you want to allow these enchantments to be influenced by candles you'll need to add them to the "Influences List" section of the config.
