Use Nunu & Willump's superior clear speed and objective control to pressure early dragons and Rift Heralds before Ivern can react.
Focus on leveraging (W) for unpredictable ganks through fog and force Ivern's team to ward deeper, denying him safe pathing and camp access.
Jungle Plan
Prioritize invading Ivern's opposite side jungle when lanes have priority to deny his buff shares and camps.
Use (W) angles from fog to gank repeatedly and convert successful ganks into immediate dragon or Rift Herald attempts.
Track Ivern's unusual pathing to counter-gank effectively and secure river vision to control objective setups.
Danger windows
Be cautious contesting objectives when Ivern's lanes lack priority, as he can use (Q) root and (R) knockup to turn fights.
Avoid fighting in isolated river skirmishes without vision and lane support to prevent getting caught by Ivern's CC and Daisy.
Watch for low-health clears where Ivern can capitalize on your reduced sustain and force smite fights.
Early game
Start with a fast full clear using (Q) to maintain health and tempo, aiming to reach level 3 quickly for early river control.
Contest first Scuttle only if nearby lanes have priority to support and prevent Ivern from safely sharing buffs.
Avoid isolated 1v1 fights early; instead, path to gank lanes where (W) can create numbers advantage and follow up with CC.
Power spikes
First dragon or Rift Herald spawn: use (Q) plus Smite to secure objectives quickly and force fights on your terms.
Level 6: layer (R) after (W) or ally CC to maximize zone control and punish enemies caught in your CC chain.
Respect Ivern's (R) knockup and (Q) root as windows where engaging without lane support risks losing fights.
Win conditions
Convert early ganks and lane priority into fast objective control using (Q) plus Smite to snowball map pressure.
Deny Ivern free farm and buff shares by invading when lanes can assist and using (W) to create unpredictable gank angles.
Use your strong objective control and CC chain to force teamfights around dragons and Herald, enabling your team to close out games before Ivern's utility scaling peaks.
