Best thing to do is spend time focusing on your rotation (target dummy practice) until you've got it down by muscle memory. This will boost your awareness as you don't need to spend much attention to what you plan on doing next. Use this awareness to pay attention to what the boss is doing and enviornmental hazards. Recognize patterns in the boss behavior (you can learn when a wicked wheel is coming from garuda for example) to avoid unecessary damage. Eventually you'll learn when it's safe to activate blood for blood and your jumps.
