Playing against Leblanc

How to counter and exploit weaknesses

1

When LeBlanc dashes with W, her return position is visible (distortion on the ground) — place your CC at that spot.

2

Buy MR and HP: her burst is 100% magic damage and she can't fight if she doesn't one-shot.

3

Punish her when her W is on cooldown (18-10s): it's her only mobility and approach damage source.

4

Champions with shields or sustain counter her short burst pattern — she can't trade for extended periods.
