Greater Fire Protection Potion Recipe Farming Location (Classic - WotLK)
The Recipe for Greater Fire Protection Potions is found in Lower Blackrock Spire, it drops off of a Firebrand Pyromancer and Firebrand Invoker. The Firebrand Pyromancers also have a chance of dropping the Robe of the Archmage Pattern which is a valuable pattern as it crafts a highly sought after robe for Mages.
In order to farm the Greater Fire Protection Recipe you'll need a group, depending on their gear and skill you may not need a full group to farm it. The enemies that drop this recipe aren't too far inside of the dungeon from the entrance; you'll need to take a short cut though and drop down by the lava once you're inside.
You'll find the area you need to drop down at shown in the screen shot below. Where I am standing at is in the first very large open room that you come across after clearing the first few pulls of the dungeon. For a video of me following this exact route down check out my youtube video. That will offer you better guidance than a written guide.
After you drop down to the area below you'll be in the same location that the Bannok Grimaxe rare NPC spawns which drop the Arcanite Reaper plans. This area is a messy cluster of enemies and you'll find Firebrand Invokers all throughout here. It'll be a difficult area to get through it without some serious CC or a really well geared group. Our destination is the area right before the spiders in LBRS.
There is a very small alcove to the right of the spiders (pictured below) which has Firebrand Pyromancers in it which drop the Pattern: Robe of the Archmage. This is the only location in the entire dungeon that drops the Pattern: Robe of the Archmage and I highly recommend that you clear this alcove every single time that you come to this dungeon.
