If slaughtering is too fast... accidents happen. Wrong animals are killed, etc...
If slaughtering is too slow (as it is)... culling the herd is one of the most boring activities in the game.
So here is my suggestion: Slaughter Mode!
When in "slaughter mode", you slaughter animals very, very fast. (at least twice as fast - it's currently too slow)
Here are three possible ways/suggestions for Slaughter Mode to work:
- A new Toggle. Just activate it to have faster slaughtering.
- Based on player pattern. Slaughter mode could be a "buff" that gets activated after slaughtering (for example) 3 animals in a short window of time (like 5 minutes). The game would "Notice" you're working on culling animals and you'd get the buff, making slaughtering the next animals way faster.
- Based on tool. Possibly the butcher's knife - if you're using one, slaughtering is accelerated.
Edit:
One extra possibility:
- Hearth Magic, gives you a temporary "blessing" (buff) to slaughter animals faster. Could have a sacrificial theme to it. Preferably not so expensive.
