Lane harass pressure and late-game off-carry damage.
Empowered abilities and resource manipulation
Hitting a champion with spells hurls a comet that deals adaptive damage at them. Landing more spells reduces Arcane Comet's cooldown.
Periodically your next ability used has its mana or energy cost refunded and restores some of your missing mana or energy.
Gain 3% extra MS. Gain extra AP or AD, based on your bonus MS, Adaptive.
Gain increasing amounts of AD or AP, Adaptive over the course of the game.
+20 Ability Power or +12 Attack Damage, Adaptive
Deals bonus true damage to enemies with impaired movement or actions.
After killing an enemy ward, a friendly Zombie Ward is raised in its place.
Miss Fortune Support relies heavily on her [E] in the early game, making Comet a guaranteed hit thanks to the slow. [E] spam with Comet and Cheap Shot results in fantastic lane pressure damage.
Manaflow Band allows you to keep up your [E] harass and poke in the laning phase without fear of running out of mana.
Celerity is a fantastic rune choice on Miss Fortune as the bonus Movement Speed from you [W] as well as Phage/Black Cleaver grant you a bit of bonus AD (AP in the early game).
Gathering Storm is a great rune choice for scaling into the lane game as a secondary carry. In a 30min + game where you are able to hit level 16, you're as big of a threat as any of your solo laners.
If you want to double-down on lane pressure, take Scorch here instead.
Cheap Shot on MF is taken as a lane harassment option as you're able to instantly proc the bonus damage easily with [E].
Zombie Ward is an all-around great support rune choice. It's effectiveness scales incredibly well with Sightstone and the raw number of wards you place down over the course of the game.
