Cauldron of Major Frost Protection

Requirements to make a discovery

You must be crafting a potion, elixir, flask or performing a transmutation that was adding in TBC.

As a rule of thumb that's anything that is learnt from a master alchemy trainer, dropped from a mob in outland or purchased from a vendor in outland. The only real exceptions are the pre-TBC flasks that have been made available from faction vendors in outland.

I recently made enough "Major ... Protection Potions" to discover all the "Cauldron of Major ... Protection" recipes. Here are my results (of course, your mileage may vary):

• 
  
• Cauldron of Major Arcane Protection (5 casts of Major Arcane Protection Potion ie. 25 potions)
• 
  
• Cauldron of Major Fire Protection (6 casts of Major Fire Protection Potion ie. 30 potions)
• 
  
• Cauldron of Major Frost Protection (1 cast of Major Frost Protection Potion ie. 5 potions)

• Cauldron of Major Nature Protection (5 casts of Major Nature Protection Potion ie. 25 potions)
• 
  
• Cauldron of Major Shadow Protection (3 casts of Major Shadow Protection Potion ie. 15 potions)

This suggests that there is about a 25% chance of discovering the associated "Cauldron" recipe, each time you make a "Major ... Protection Potion".
