How to beat Janna as Xerath: the early game

You own the early lane: you're the only source of damage, so W-slow and Q-poke Janna or her carry relentlessly, especially while her Howling Gale is charging and easy to dodge. Every level 1-3 trade is free pressure toward an early lead. Her gust cancels your carry's follow-up rather than your poke, so keep chipping from maximum range. Hold the stun for the moment her disengage is already spent, use the slow-zone to pin her carry in place, and watch the mana bar as the lane goes long.
