Purple Ice Bear
Can Be Tamed
The Azure Span
Spawning this bear is quite complicated. Firstly, you must have the Skinning profession and have levelled Dragon Isles Skinning to the point where you can select the Bait Crafter specialization (see your skinning journal inside your professions panel). You need to spend at least 10 points of Knowledge in Bait Crafter, then select and spend 20 points in the Mastery subspecialization, which will give your bait a chance to summon an Elite NPC (but don't advance your Mastery to 40 or you'll mostly summon a rare NPC and your chance of getting this bear will drop dramatically!). Once you've reached this rank in both Skinning and Mastery, craft an Elusive Creature Bait and use it in an area where ice bears can be found in The Azure Span (around 64, 29 is a good spot). The bait will randomly summon one of a range of NPCs, so it may take a lot of tries to attract an Elusive Rimeclaw, and likely many more times to get it in the colour you want. While the base cooldown on using the bait is 12 hours, you can reduce it by at least 10 minutes for every creature you skin (this reduction improves as you advance Mastery). So if you go to a common killing area you might be able to reset it in 15 minutes or less. It's also possible to use the bait to summon the bear for a friend to tame, though the low chance of it appearing means they might be waiting a long time. See Wowhead's Dragon Isles Skinning Guide for an overview of how this profession (and the Bait Crafter spec) works in Dragonflight. The guide also tells you how to gain the Knowledge points you'll need to advance your specialization.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
