As an explorer of dangerous places, you are trained to react to danger swiftly and adroitly, as well as navigate Difficult Terrain, and reduce damage.
If you are hit by an Area Attack, you take half damage if the attack hit you. If the area attack misses you, you take no damage.
Extreme Effort Edit
When you use the Run action, you can move up to five times your Speed (Instead of up to four times).
Your Speed is not reduced by Difficult Terrain.
