Glad you managed to get this done. I am still waiting to complete this so if anyone fancies it give me a shout and we can continue from the death singers checkpoint.
Happy to help out with CoO if you want to do it tonight before boss's change over.
The scent one is a pig to do, although it is doable solo it really is about timing and trying to reduce the amount of time you have the ghost open to reveal the platforms (as well as have max agility and hold a weapon with agility boast to help move that little bit quicker). Although having people on the platforms usually helps. As long as you can get to the final section with around 12 seconds to spare you should be able to open up the chest.
Hey Dave, of course I'm always around to help with the raid if you need me. And if I need u for Coo I'll give u a shout.
Just want to get my ToM
