Anatomy
Anatomy skill is knowledge of the inner workings of the body. This skill is automatically applicable to the character's race as well as all of the common, humanoid races of the world, including humans, elves, dwarves, halflings, half elves, half orcs, orcs, kobolds, goblins, ogres and giants. It is also applicable to animals and monsters if the character also has Animal Lore and Monster Lore roll.

Anatomical Knowledge
The character has an Anatomical Knowledge roll equal to ((KNOW - 15) x 3) + (Rank x 5). If the character has Animal Lore and/or Monster Lore, use the lower rank of the lore skill or this skill to compute bonus when applied to animals and monsters.

Cause of Death
The character is able to determine a cause of death with a successful skill roll equal to (((INT + KNOW) - 30) x 1.5) + (Rank x 5). Note that if the cause of death is poison, and the character has no skill with poison lore, they will not be able to determine anything beyond that the target was killed by some sort of poison. This is similarly true with out types of death that are not directly trauma related such as some save-or-die spells.

Dissection
The character's chance to cleanly dissect a target, perhaps to remove their heart or a poison sac from an animal, is equal to ((DEX - 15) x 3) + (Rank x 5).

First Aid
Each rank of Anatomy skill provides a +2 bonus to First Aid rolls.

Surgery
A character with both Anatomy and First Aid skill can attempt surgery. This is normally done to repair a grievous wound that requires a Cure Serious Wounds or Cure Critical Wounds spell and the group does not have one. Surgery roll is (((DEX + KNOW) - 30) x 1.5) + (Rank x 5) using the lower of Anatomy or First Aid skill rank. It takes 1 hour to perform surgery to repair a wound that would normally require a Cure Serious Wounds and 4 hours for a wound that would require a Cure Critical Wounds. Recovery time is 48 hours in the former case and 96 hours in the latter case unless a Cure Light Wounds is cast immediately after the surgery to heal the damage caused by the surgery. In this case, no additional healing is done but the recovery time is immediate. Recovery time is also modified by the character's normal healing rate. Someone who normally heals 2 points a night takes only 24 hours (or 48 hours for CCW) to recover after surgery.

The character must have suitable tools to perform surgery. These include, at minimum, a couple of very sharp knives and some bandages.

Lay Healers
Note that Lay Healers may develop this skill with a multiple of 75.
