Are there any mobs that drop Apexis Crystals, I looked everywhere but cant find anything on this

Alright thank you, i was also wondering if there’s a super easy way to get Garrison Resources
Depends. There is a really easy way if you have any gold to spend and are lazy. You can buy these https://www.wowhead.com/item=128313/huge-ogre-cache from the auction house and instantly get a 1000 resources. I think the prices vary greatly depending on your realm, though.
