The Tournament and the Timeless Isle have been such a huge topics that I’m writing this post to link everything for easy bookmarking and reference. I’m also going to put the comprehensive pets checklist for all the triads and all the Celestials below. This is almost as much for your benefit as it is for mine. I think I’m still missing a grub.
Below are also links for some videos of a few new pets you can collect in 5.4. I haven’t posted them on the blog until now! The screenshots are extras I took, mostly pet-related, from the 5.4 PTR.

Xufu is mine! Thanks for the guides, these were really helpful! :)
Yay & congrats!
Hi Liopleurodon, fellow Crazy Cat Lady here. Loved the guide. Yu’la strat especially helpful, as despite supposedly being the easiest of the Celestials, I found her to be the hardest because of RNG. Have included the Yu’la basics on a forum guide for my guildies – hope that’s ok – you’ve been given a special mention and thanks (and encouragement for people to come check out your excellent blog). And Xu’Fu is also now mine – yay!
Of course! Thanks for reading, and congrats on Xufu!
Finally finished this tonight (a little late to the party, but hey) – fantastic guide, thanks for all the hard work!
