Was going to post this idea for a killer, came across the recent great 'Beekeeper skin' idea for the clown, so almost didn't, but figure it's different enough.
Chapter: Sweet the sting
Killer: The beekeeper
Weapons: Bellows and Blade
Traps: Hives and honey
How it works:
Like generators or Divine Pools, beehives are dotted around the map. These are initially harmless, but can be stoked with the bellows to start angering the bees.
Honey traps can be smeared on objects and gens, which attract bees. These are harmless, and the stickiness wears off over time. However it can get stuck to survivors for short periods of time.
Like corrupt intervention, once a hive errupts, the angry bees escape and head for the nearest honey traps. Contact with bees causes screaming and a wound. (But they are a visible cloud than can be dodged, or ducked under.)
Survivors with honey on them scream and have a delayed swatting action (like the Trapper's trapees), taking a hit before escaping.
The beekeeper themselves is relatively slow, relying on nimble bees and strategic honey to wear down survivors.
