Camille should focus on using terrain angles to threaten (E) and control short trades with second (Q) to avoid Jayce's poke damage.
Prioritize medium lane pressure to deny Jayce a passive, ranged poke lane and scale into a side-lane splitpush threat.
This is a scale versus snowball matchup where Camille aims to outscale Jayce by punishing oversteps and locking down targets post-level 6.
Trading pattern
Trade only when second (Q) is primed and use (E) for confirmed terrain engages to maximize burst and disengage safely.
Punish Jayce after he uses hammer form (E) knockback or misses empowered (Q) poke by stepping forward for short trades.
Avoid long trades where Jayce can leverage his poke and ranged pressure to out-sustain you before your item spikes.
Danger windows
Be cautious when (E) is on cooldown, as Camille loses both engage and escape options, making her vulnerable to Jayce's poke and hammer form engages.
Avoid extended trades before your first item spike, as Jayce's ranged poke and hammer form burst can overwhelm you.
Watch for Jayce's empowered (Q) through (E) poke, which can set up lethal trades if Camille is low or poorly positioned.
Early game
Use early waves to position near terrain for safe (E) engages and avoid extended trades before item spikes.
Respect Jayce's ranged poke and avoid taking unnecessary damage before second (Q) is ready.
Focus on short trades that land the second (Q) true damage and back off before Jayce can retaliate.
Power spikes
Camille's first sheen-style item spike allows reliable second (Q) trades and side-lane pressure; use this to force short trades and disengage before Jayce can respond.
At level 6, use (R) to lock down Jayce after baiting his disengage, preventing his escape and securing kills.
Respect Jayce's first damage item spike and mid-game poke siege, as his empowered (Q) plus (E) poke can quickly punish overextensions.
Win conditions
Use terrain to threaten (E) engages and force short trades that capitalize on second (Q) true damage.
After hitting item spikes and level 6, pressure side lanes to isolate and pick off Jayce or his teammates using (R) lockdown.
Deny Jayce passive scaling by punishing his poke cooldowns and avoiding prolonged trades, then leverage Camille's superior late-game dueling and splitpush.
