Boghopping

Unless you are born of it, a swamp will try to absorb you into its mud. This Subskill increases your chance of finding the basics of life within a swamp or marsh. Ranks in this Subskill will increase your ability to survive in a place naturally hostile to outsiders. This Subskill bonus is applied to any standard Survival check you make while in a swamp; however, its bonus can also be applied to other Subskills you may have (Such as Tracking when in a swamp, if you also have a Tracking Subskill bonus.) When you rank increases to 2, you may treat one square of difficult terrain as regular terrain during each of your movement actions. Additional bonuses will be unlocked at ranks 4 and 6 of this skill.
