Do

  • E-chip every contact
  • Bank Q for the real window
  • Laser the rooted refund

Don't

  • Q-poke into their shields
  • Trade at their sustain tempo
  • Barrier the chip

Levels 4-5LuxThrough 4-5 you dictate poke while she plays passive defense.
Level 6LuxYour level 6 R nuke threatens her squishy carry across the lane.

How to beat Janna as Lux: the early game

You dominate the early poke war: Q outranges Janna's shield-poke and a level-2 E-Q chunks her before her tornado is ready, so she can only sit back and shield. Your reach beats her shield-poke and the level-two rotation chunks her before her disengage matters. Drop the zone on the ground she has to hold, and save the root for the moment her gust is spent rather than firing it into a lane where she can simply walk out.
