Hostility spikes, often triggered by opening dangerous glades or the onset of the Storm season, can feel like a sudden 'boss attack' on your settlement's morale. High Hostility directly impacts villager Resolve, making them more likely to leave. Proactive management is essential to weather these spikes.
During periods of high Hostility, prioritize boosting Resolve through luxury goods, services, and Hearth upgrades. Consider temporarily reducing the number of woodcutters to lower Hostility. Have a buffer of food and fuel. If a glade event is causing a spike, resolve it quickly. Sometimes, accepting a small penalty from an event is better than letting Hostility spiral out of control.
