Use Moonfall and Lunar Rush to stay on targets and activate Moonsilver Blade for extra damage.
Consider when to cast Lunar Rush without Moonlight and when to wait for another Crescent Strike.
Landing Crescent Strike is critically important, but don't be afraid to miss. The cooldown is short and the mana cost is low.
