Felycle Puzzle - Step 6 Altars

Hey all, working my way through the felcycle steps and feeling a bit stuck on step 6, think Im missing out on stuff via garrison and covenants which I played least and are very timegatey. Has anyone done this step/has the requirements and doesn’t mind teaming up so I can clear this step off? Would appreciate it!

This is what I’m talking about as I’m sure everyone knows https://www.wowhead.com/guide/secrets/ratts-revenge-incognitro-felcycle-guide#6-oclock-altars
