Focus on safe full clears to reach level 4 before contesting Scuttle or fighting Rek'Sai to avoid her early high pressure and gank threat.
Prioritize river vision and only contest Scuttle when nearby lanes have priority to limit Rek'Sai's tunnel gank angles and early invade potential.
Jungle Plan
Secure top-side camps and contest Scuttle only when your lanes have priority and Rek'Sai is not nearby to avoid losing numbers.
Invade Rek'Sai's jungle only after gaining a tempo lead or when she is committed on the opposite side of the map.
Coordinate with lanes holding priority to control dragon and Rift Herald, denying Rek'Sai early objective advantages through vision and numbers.
Danger windows
Rek'Sai's early three-camp clear and level 3 gank window create high invade and counter-gank risks; avoid isolated river fights before level 4.
Contesting Scuttle without lane priority is risky as Rek'Sai can reinforce quickly through tunnels.
Low-health clears or forced smite fights before your level 6 power spike leave you vulnerable to Rek'Sai aggression.
Early game
Start with a full clear to hit level 4 safely, avoiding early fights where Rek'Sai's level 3 gank power is strongest.
Avoid early river skirmishes unless your lanes have priority and Rek'Sai is visible on the opposite side to reduce counter-gank risk.
Track Rek'Sai's three-camp path to anticipate her early ganks and position for counter-ganks or safe farming.
Power spikes
Level 6 grants durability and sustained damage, enabling you to contest objectives and extended fights; use this to challenge Rek'Sai's early aggression.
Two-item spike significantly boosts your splitpush threat; force Rek'Sai to respond to side-lane pressure and open map for your team.
Respect Rek'Sai's early level 3 and tunnel gank power before you reach your level 6 and item breakpoints to avoid unfavorable fights.
Win conditions
Use side-lane priority after your two-item spike to force Rek'Sai to respond, creating space for your team to secure objectives.
Leverage vision control and tracking to counter-gank Rek'Sai's tunnel ganks, denying her snowball potential.
Prioritize dragon and Rift Herald with lane priority to capitalize on your scaling dueling power and prevent Rek'Sai from gaining early objective leads.
