The eagle will need to find 1/10 of its body weight in food per day, which it will do by hunting animals and/or eating carrion. If an eagle fails to eat enough in one day, it weakens.

Circe's rules on starvation (and dehydration) are as follows:


A health check must be made each day [that the character is not fed]. If failed, the maximum fatigue level allowed to the character is reduced by one and the character takes d3 hp damage.


The [humanoid] body needs about 5 quarts of water each day, less if the level of physical activity is low, more if in a hot, dry climate. A health check must be made each day, penalized by two points for each day spent without water. If failed, the maximum fatigue level allowed to the character is reduced by one and the character takes d6 hp damage.

Hunting for Food

The eagle will have two choices: circle in the air or perch on something and wait.

Perching is simple. The eagle lands on a suitable object and waits. During this time it may be ambushed by a predator.

Circling may be more complex. The player should be able to choose a height at which to circle, which may affect the area which the eagle can search. It may also affect the eagle's ability to notice smaller targets. Also, the sight of an eagle in the air may frighten away more timid prey. More agressive prey may note the presence of the eagle and prepare to defend itself, or launch an attack of its own.

When prey is detected the eagle may ignore it or attack it. Combat will follow the Circe rules.

  1. First, the eagle swoops down on its prey. If the prey was aware of the eagle, it may attempt to Dodge or Tumble from the eminent attack, or launch an attack of its own.
  2. The eagle attacks with a Grapple attack, using the appropriate Terrestrial, Aquatic, or Aerial attack value. If the attack fails, the eagle's talons close on empty air. The eagle must circle around and swoop again. The prey is definitely aware of the Eagle's presence at this point, and an attempt to flee is likely.
  3. The Grappled prey is allowed to Resist, attempt to Free itself, or counterattack.
  4. If the Grapple is maintained, a Maul attack is made on the target. A successful Maul also does bite damage.The eagle will get a "locked bite" of the prey (meaning the bite will grab a hold of the prey with beak) and then it must rip the flesh out ("ripping bite"). According to Circe the damage done by the ripping bite is the better of two damage rolls.
  5. If the prey is light enough for the eagle to carry (1/2 the eagle's weight) and the Grapple has been maintained, the eagle has the option of carrying the prey into the air. If the prey is too heavy, the eagle may engage it in continued ground combat, or release its Grapple and swoop again.

If live prey carried by the eagle (a snake, for instance) becomes troublesome, the eagle may release its Grapple, allowing the prey to fall to the ground, and possibly its death. While being dropped from a greater height inflicts greater damage, it also increases the difficulty faced by the eagle in locating the possibly dead prey. This also applies to living and dead animals, and even carcass chunks, that somehow manage to wriggle free of the eagle's claws while the eagle is in flight.


The amount of food that an animal provides the eagle depends on both its Size and its Food Value. See the animal list. Use the Food Value table below to find what percentage of an animal's mass (given by its Size) is edible by the eagle.
Food Value
BadPoorFairGoodVery Good
An eagle cannot carry more than 1/2 of its own weight. Prey heavier than this must be broken up into pieces of 1/2 the eagle's weight, or less, in order to be carried by the eagle. We can assume that the eagle only carries away edible portions of prey, so the remaining carrion would (after the eagle leaves) would have a food value of (Size/Food Value)-(1/2 Eagle's Weight).

Any portion of the prey left behind by the eagle automatically becomes carrion. Carrion loses a portion of its nutritional value every night, and at the same time, gains a chance of causing disease. This continues until the carrion rots away into nothing.

Suggestion for decay of carrion: Amount of meat lost per (turn | time unit | minute | etc.) is proportional until a certain limit limit is reached, when the carcass is assumed to have rotted away. Probability of infestation with a certain disease is proportional to time since death. -- Steven.
