Prioritize full clears to hit level 6 on schedule and leverage Nocturne's strong dueling and gank threat post-ultimate.
Use (R) to punish overextended lanes and create cross-map pressure for objectives.
Manage fights around your (W) spell shield to mitigate Gragas's burst and displacement threat.
Jungle Plan
Path camps toward level 6 focusing on efficient clears to maintain tempo and objective control.
Contest Scuttle Crab only when nearby lanes can support to prevent Gragas from using (R) to isolate or disengage.
Use (R) to gank overextended lanes and convert picks into dragon or Rift Herald pressure, avoiding blind invades against (E) stun and (R) displacement.
Danger windows
Avoid fighting when (E) and (R) are available as he can stun and displace you, breaking your engage.
Beware of isolated river fights where Gragas can use (R) to split your team or knock you into danger.
Do not contest objectives without lane priority or vision control to prevent Gragas's disruptive ultimate from turning fights.
Early game
Start with a full clear to reach level 6 quickly and maintain objective access.
Fight for first Scuttle only if nearby lanes have priority to avoid multi-lane collapses.
Avoid early river brawls unless you have vision and lane priority to counter (E) engage and (R) displacement.
Power spikes
Level 6: Use (R) to create picks and force Gragas into unfavorable positions before objectives.
Full clear completion: Enables timely ultimate pressure and objective setups.
Gragas level 6: Respect his (R) displacement which can disrupt your engages and isolate you from teammates.
Win conditions
Convert level 6 ultimate picks into dragon and Rift Herald control by coordinating with lanes that have priority.
Use your faster clear speed to pressure Gragas's jungle and deny him scaling by invading when his key cooldowns are down.
Leverage your dueling strength around (W) to win 1v1s and snowball leads into objective advantages and map control.
