Just a heads up: you can now tame a spirit beast earlier than the previous minimum level requirement of 74. It's a lightning fox called Lightning Paw that spawns in Duskwood. I'm currently unsure of it's level. When I found it on my level 70 hunter it was level 70, which means that it's highly likely that it scales with your level (since i find it unlikely that it's a level 70 mob in duskwood). But even if it does scale to your level it might have a minimum level like Broken Isles mobs. It can be found in stealth inside bushes that have the blinking eye animation: But keep an eye on the wowhead comments where people are slowly discovering more known locations and other useful info on how to find it. It has Spirit Mend and Spirit Walk just like the other spirit beasts.
