I've put off doing COX for a very long time. Group content intimidates me. I've done a couple hundred solo TOA though, am I am lucky enough to have a couple pieces of Masori as well as the Shadow. I also have an imbued heart.

Sooo...do I rush right into Muspah with only an RCB for sapphire bolting, or do I bust out some bowfa Sara first and get the RCB?

Do I do my Aviansie slayer task now with the 5k black chins I have and get partial fortified Masori and that pesky master clue step out of the way? Or diving into COX first and get Rigour, and I suppose Augury too?

Big decisions? What grinds are worth it first? I have my own ideas but I'd love to hear what you guys think.
