Bog hags stake out a territory in a given body of water near a human community and wait for potential victims to approach the water. A bog hag rarely attacks unless its victim is alone, in which case it swims up behind its prey and attacks in the water.

Disease (Ex): Bog rot-claws, Fort save (DC 13), incubation period 1d4 days; damage 1d4 temporary Con (see Disease).

Improved Grab (Ex): To use this ability, the bog hag must hit with both claw attacks. If it gets a hold, it can drown the victim.

Drowning (Ex): Once a bog hag has a hold on a victim, it swims underwater and attempts to drown the character. (See Water Dangers)

Alternate Form (Su): A bog hag can alter its appearance as if using the alter self spell. However, it can only take on the appearance of specific individuals, and only by stealing and then wearing their skin. When a bog hag dons a victim's skin, an innate supernatural ability conforms its body to the shape and appearance of the victim. The skin, however, rots as the body decomposes (barring tho application of a gentle repose spell), making it useless within a week of the victim's death.

Fast Healing (Ex): A bog hag that takes a new skin heals 2 hit points per minute until it reaches its maximum hit points. Once fully healed, the bog hag does not heal more quickly than normal until it dons a new skin.

Fire Vulnerability: A bog hag takes double damage from fire unless a saving throw for half damage is allowed, in which case it rakes half damage on a success and double damage on a failure. A bog hag tends to flee if an opponent brandishes flame at it.

Skills: A bog hag gains a +4 racial bonus on Bluff and Disguise checks. When using its alternate form ability, the bog hag gain an additional +10 circumstance bonus on Disguise checks.

Shadowlands Subtype

Shadowlands are the source of evil in the campaign setting of Rokugan, the festering pit from which oni crawl, slither, and fly to wreck their foul destruction on humanity. The denizens of the Shadowlands are inhuman monstrosities. Many of them are spirits bound into corporeal form, and most are shapeshifters. Of all the creatures found in the Shadowlands, only the nezumi remain uncorrupted by the foul taint of the place - all others are utterly, irredeemably evil.

Shadowlands creatures share a certain immunities and vulnerabilities. They are immune to harmful effects of the Shadowlands Taint, for they are already fully corrupted by their very nature. Even if they have damage reduction, they are harmed by jade and obsidian weapons, and they cannot regenerate or naturally heal wounds dealt by such weapons. They are also affected by crystal weapons (Chapter 8, Oriental Adventures) (Note: Non-magical weapons made out of crystal, or crystal weapons created by means other than the Craft Crystal Weapon feat, have no special properties against Shadowlands creatures.)

For purposes of detect Taint, spellcasting, and other effects, a Shadowlands creature is considered to have a Taint score equal to half its Charisma score (round down). Undead creatures add +1 to this number, while outsiders add +2.

Shapechanger Subtype

A shapechanger has the supernatural ability to assume one or more alternate forms. Many magical effects allow some kind of shape shifting, and not every creature that can change shapes has the shapechanger subtype.

Traits: A shapechanger possesses the following traits (unless otherwise noted in a creature's entry).
