Arcane Comet on Camille is a non-obvious but strong keystone choice for Camille thanks to the high hitrate from the strong slow of [W] and the stun from [E].
Manaflow Band on Camille allows you to repeatedly take trades in lane and out-sustain your opponent thanks to the large heal from [W].
Absolute Focus' extra stats in lane make for fantastic lane bullying and applying pressure for more damage and kill potential.
Scorch is the go-to lane harass rune for getting an early lead in damage so you can keep your opponent in kill-range.
Demolish massively empowers your ability to late game split push.
Second Wind allows you to further enable your early laning trades and synergizes extremely well in lane with Iron Skin. Paired with a Doran's Shield you should be able to sustain heavy amount of poke and harass damage.
