Danger Zones
During an adventure, resting restores hit points and other limited resources, but when and where characters can safely rest is just as important as how much they recover. This system uses Danger Tiers to represent how hostile or unstable an area is, with Tier 1 representing secure, civilized environments and Tier 5 representing extreme danger such as deep dungeons, active warzones, or hostile wilderness.
Each cycle of time spent resting in an area carries a chance of interruption or escalation (random encounters), meaning threats scale rapidly as adventurers push deeper into perilous territory. This framework prevents resource exploitation in unsafe areas, encourages strategic retreats and forward bases, and reinforces the narrative reality that civilization provides safety while the unknown is inherently dangerous.
The CR of dangers is also based on Danger Level.
1 = APL -1d3
2 = APL -1
3 = APL
4 = APL +1
5 = APL +1d3
Story exceptions apply, this is only for random encounters which serve as resource drains while you attempt to rest or do downtime activities or exploration.
