Start with a shield lob on your way to the mob that you want to catch, by the time that you get there, your cooldowns will be ready. Throw a flash at it, then drop circle of scorn, then flash again, then spirits within, then commence your Halone combo (This is gross overkill for most scenarios, but it's the fastest way to stack your enmity). If you need to recover it from somebody that took it too quickly, use provoke on it to give yourself top-tier hate, then shield lob it to secure your pole position on the enmity gauge and proceed as you normally would.
