Rek'Sai must leverage her superior early clear speed and high early pressure to invade and deny Rammus farm before he scales.
Focus on controlling river Scuttle and objective entrances with tunnels to outmaneuver Rammus's slower clear and lower invade resistance.
This is a snowball matchup where Rek'Sai aims to snowball leads through early ganks and camp denial before Rammus's late-game tank scaling kicks in.
Jungle Plan
Prioritize invading Rammus's jungle early, especially if your lanes have priority to back up aggressive plays.
Fight for first Scuttle only when nearby lanes can move first to secure river control and deny Rammus vision.
Use tunnel paths to set up repeat ganks on flashless or immobile lanes before Rammus can respond or reach power spikes.
Danger windows
Avoid isolated river fights when Rammus has (Q) rolling engage available, as his knockup and taunt can turn fights.
Be cautious contesting objectives if Rammus's lanes lack pressure and he can arrive first with (Q) speed.
Rek'Sai is vulnerable during low-health clears or after unsuccessful invades without lane support; reset tempo to avoid forced smite fights.
Early game
Start with a three-camp clear into early river Scuttle to contest vision and deny Rammus's slower pathing.
Use tunnels to quickly cross-map and punish Rammus's predictable three or four-camp pathing toward overextended lanes.
Avoid extended fights early if Rammus has lane priority or taunt ready; instead, focus on counter-ganks and objective setups with lane priority allies.
Power spikes
Rek'Sai spikes at early levels with fast clears and (W) knockup enabling strong ganks; use this to force Rammus off camps.
Rammus becomes more dangerous when (Q) and (E) are up for fast engages; respect his taunt timing to avoid getting locked down.
Rek'Sai's ultimate (R) provides execute and chase potential; use it to finish off targets escaping Rammus's taunt or speed engages.
Win conditions
Convert early jungle tempo into repeated ganks using tunnels to snowball lanes before Rammus scales.
Deny Rammus free farm by invading his jungle camps when lanes have priority and contesting Scuttle vision.
Use early numbers advantages to secure dragons and Rift Herald, leveraging Rek'Sai's mobility and objective control to close out before late-game tank scaling.
