Rammus should leverage his strong gank threat and taunt to pressure overextended lanes early against Fiddlesticks' slow early game and weak dueling.
Prioritize disrupting Fiddlesticks' fast clear tempo by invading early camps only when lane priority supports safe counter-jungling to deny his level 6 power spike.
Jungle Plan
Path aggressively toward overextended AD-heavy lanes to punish with (Q) engage and (E) taunt before Fiddlesticks reaches level 6.
Contest Scuttle Crab and river vision only when allied lanes have priority to safely deny Fiddlesticks' setup for objective fights.
Use cross-map ganks and counter-jungle camps when Fiddlesticks commits to full clears or resets, exploiting his slower clear speed and low invade resistance.
Danger windows
Beware early invade attempts from Fiddlesticks when lanes lack priority; avoid overextending without vision.
Isolated river fights post-level 6 are risky due to Fiddlesticks' (R) ambush and (Q) fear; prioritize vision control.
Low-health clears or forced smite fights near objectives are dangerous; only contest when teammates can assist or when you have superior vision.
Early game
Start with a three- or four-camp clear aimed at lanes with priority to enable early cross-map ganks before Fiddlesticks hits level 6.
Avoid early river fights unless nearby lanes can assist, as Fiddlesticks is vulnerable pre-6 but dangerous post-6 with ultimate ambush.
Secure first Scuttle when lanes have priority to deny vision and limit Fiddlesticks' objective control setup.
Power spikes
Rammus spikes with early (Q) and (E) for fast ganks; use these to punish Fiddlesticks before his level 6 ultimate.
Respect Fiddlesticks' level 6 spike when his (R) enables high-impact ambushes; avoid isolated river fights post-6.
Rammus scales into a late-game tank with taunt lockdown; focus on reaching this state to counter Fiddlesticks' teamfight threat.
Win conditions
Convert early gank pressure into objective control by securing dragons and Rift Herald with lane priority and vision dominance.
Deny Fiddlesticks free farm and level 6 by invading camps when lanes push and punishing his slower clear speed.
Use your taunt and engage to lock down key AD carries in teamfights, leveraging your scaling tankiness to neutralize Fiddlesticks' magic damage threat.
