Main idea

Stabilize vs the initial Spider Kitten and prepare for her spawn-in behind the killer.

Biggest mistakes

Treating her like a DPS dummy: every hit can spawn more bodies and steal tempo.
Hitting from behind at the wrong time: enrage spikes movement and collapses your lanes.

Winning line

You keep spawn pressure under control (kills/clears keep the board breathable).
You avoid accidental back-hits unless you are ready to survive the enrage turn.

Opener

Stabilize vs the initial Spider Kitten and prepare for her spawn-in behind the killer.

Run killers

Treating her like a DPS dummy: every hit can spawn more bodies and steal tempo.
Hitting from behind at the wrong time: enrage spikes movement and collapses your lanes.
Failing the add-check when she goes off-board: you lose control while waiting for her return.

Positioning rules

Do not clump: web + trample + spawns punish tight packs.
Keep at least one lane open for retreat when she returns behind/next to the killer.
If you must hit from behind, do it only when you can absorb an immediate tempo spike.

Loadout hints

Mobility or spacing tools AOE or efficient cleanup

Over-clumped melee-only setups Single-target-only damage with no cleanup
