Wilderness Warrior

Wilderness warrior [minor] by Iczer

'Day 15. Still stranded in the jungle. It's beginning to feel a lot like home.'

The character has a survival instinct that triggers when isolated from the regular creature comforts of home. The character has an instinctive climb, prowl, swim and wilderness survival of 30% +2% per level (or +10% to these relevant skills),
Every day of isolation that the character experiences, he gains +10% to the aforementioned skills, as well as +5% to wilderness skills (skills max out at 98%; the definition of isolation is a GM discretion. Typically it refers to being abandoned in the wilderness, jungle, desert etc but could refer to a post apocalyptic urban environment as well).
In addition, the character gains +1 PE per day of isolation, to a maximum of 30.
The character heals at twice normal rate, and is highly resistant (half effect and duration) from normal environmental trauma (baking heat, dehydration, natural disease or venom, etc).
