1826 pets
It's a lengthy 14 step process to collect 13 hidden pebbles located across Kul Tiras and Zandalar. Some are in very difficult to reach locations (be ready to use some consumables).
Check out Warcraft Secrets Community Guide to Baa'l
The final step is to find Baa'l and beat him in a Pet Battle. This NPC is a Legendary pet and has an overpowered ability, Murder the Innocent.
However, if anyone nearby summons out Uuna (and has completed her continued story) she will have an interaction with him and weaken Baa'l's stats and abilities significantly, making it possible to defeat him. For a non-combat companion, Uuna sure packs a punch with her wand!
Upon summoning this pet for the first time, Baa'l has something really ominous to say. The Secrets Finding Community speculates that this could be a hint at another mystery to solve, as the letters in Baa'l's foreboding statement create the anagram, "SEEK KNOWLEDGE". We'll have to see if this leads to anything.
He can be beat at full strength but he wont drop the pet
Mini Mindslayer x2 or Transmute
Blood Boil for 3rd pet
Life Exchange & Drain Blood rotation until he dies
For those wondering about whether 'Seek Knowledge' leads to anything....

More tips for the battle with Baal,
I do say, the Uuna line is SO worth doing. Its a quest with your companion, not just having one out.
I had the Upgraded Uuna on my action bar. After I loaded my team, I pulled out my Fourth Man (Little Girl). Even Uuna mitigated, Baal hits hard. Magic based pets lasted best. I didnt try them all. Best pet, Syd 1 1 2. Cleansing Rain does damage, Bubble, and Hose him (Jet). Void pet also held up. I won 2nd time, so not much info.
Finished up and got Baal today. A couple of tips for Baal. Horseshoes for the long rides out into fatigue zones, the legendary fishing pole with fish mode for the swim down in fatigue zone. $Remove your gear$ Fatigue zone pebble #6 on the skull is on the outside back of the ship. Fatigue Cave, the last pebble is just inside to the left behind a triangular rock on the rock face. It is a dark pebble on a dark background. For most of the pebbles I was competely camera zoomed in.
How were you able to get this pet without completing the Legion storylines for Uuna? I thought those were required?
Took a long time but I finally have Baa'l! It was bugged for me so I swapped to warmode and it worked. ♥️
Is this pet a nod to Black Phillip from Witcher?
I will say this about Baa'l. If the interaction with Uuna doesn't trigger, then you need someone to use the Gastropod toy from the Thunder King raid to "kill" Baa'l.
The Gastropod user needs to only do this once. If you kill Baa'l with Jerry during Uuna's interaction with him, it will re-bug him, and he won't get reduced to a defeatable pet, as the effect on Baa'l takes a few extra seconds to work.
youre going to need Uuna and have her upgraded ( do her storylines ) and the Legion artifact fishing pole unless youre a druid and it helps to get a few shimmerscale diving suits................................................. took me right at 3 hours because of all the back and forth but .....its a baby demon goat pet....HES DEMONICALLY ADORABLE !!!!!
Well, it took a good while (longer than it should have since I didn't do the Uuna stuff in Legion), but I have my Baa'l. I thought about just hitting it with an Ultimate stone, but I think that since it took so much effort, I'm going to level it the old fashioned way.
