Confirmed scope

The FAQ discusses the three levels as existing presets. It does not provide a verified table of their names, damage modifiers, animal behaviour changes or reward multipliers.

Choosing a level without invented modifiers

Use the descriptions exposed by your installed game to select a preset suited to the challenge you want. This page does not recommend an objectively best level or claim that a harder setting improves trophy odds.

Further balancing is a plan. It is not evidence that a particular difficulty change has already shipped, and the source does not document the procedure for changing difficulty in an existing session.
