Playing against Rek'Sai

How to counter and exploit weaknesses

1

Destroy her tunnels when you find them — each tunnel is a passage she can reuse to escape or engage.

2

Her knockup (W) has short range: she must be very close to knock you up.

3

Rek'Sai is strong in the early game: respect her ganks with tremorsense. Play safe.

4

Her R makes her visible and she dashes in a straight line: a well-placed CC stops her.
