Intuitive hunch alerting you of dangerous situations or imminent threats.
You must call to the GM that you want to use part of your concentration on your danger sense. Doing so increases your passive general perception.
Roll d100 against 100 DR for +5 to your general perception. For each +10 success rate you gain extra +5.
For each concentration point you spend, you gain a bonus of +10 to your roll.
Danger Sense is a player-driven intuition check. It's not automatic—you must choose when to invoke it. Use it when you're suspicious, cautious, or suspect a trap or hidden danger. It doesn't tell you what’s wrong, only sharpens your awareness of hidden threats.
It does require spending concentration points, so it can for example limit your abiliity to move silently etc.
