Revised Gravity[edit]

This set of rule which revise the effect of various levels of gravity, and add two new levels of gravity. Despite what the name implies, it does not in fact revise the law of gravity. It was not designed to be perfectly accurate or realistic, but offer an interesting set of bonus and penalties while paying lip service to the laws of physic.

The weight of objects and creatures in listed gravity levels are variable, some plane or celestial body will have higher or lower gravity than others.

Levels of Gravity[edit]

No Gravity[edit]

In an area of constant free fall, it is difficult if not impossible to move. In effect everything is 'weightless', although that does not mean a creature can budge a particularly massive object, at least not in any noticeable metric. In effect every creatures in a area of no gravity float harmlessly, if a creature attack it take the same penalty as if it was under the levitate spell. It is possible to propel oneself using walls or other fixture, as well as magical flight or other means.

Light Gravity[edit]

In an area of light gravity, everything weight less and consequently fall are less hard than normal and movement more efficient, if ungainly. Any objects or creature in light gravity has it weight reduced to 80% to 25% of it normal gravity value. If a creature is not trained for light gravity, it take a -2 penalty on attack roll, Reflex save and Dexterity-based skill checks. On the other hand, all climb checks are halves and the distance of any jumps made in light gravity is doubled.

Falling characters in an area of light gravity plane take 1d6 points of damage for each 20 feet of the fall (maximum 20d6).

Heavy Gravity[edit]

In an area of heavy gravity, everything is heavier and thus movement and actions are more difficult to perform. Any objects or creature in heavy gravity has it increase by 100% to 200% of it normal gravity value. If a creature is not trained for heavy gravity, it take a -2 penalty on attack roll, Reflex save and Dexterity-based skill checks. Additionally any climb check doubles in heavy gravity, and the distance of any jump checks is halved. A creature's speed decrease by 10 feet in heavy gravity (to a minimum of 5 feet).

Falling characters in an area of heavy gravity plane take 1d10 points of damage for each 10 feet of the fall (maximum 20d10).

Low Gravity[edit]

Low gravity behave in the same way as light gravity except everything is even lighter. Firstly the penalties increase to a -4 from a -2. The weight of every items and creatures is is quartered to divided by 10. Any objects or creature in low gravity has it weight reduced to 25% to 5% of it normal gravity value. A creature that jumps in low gravity quadruple the distance they move and all climbs checks DC are quartered. A creature can get up from prone as a free action in low gravity.

Falling characters in an area of low gravity plane take 1d6 points of damage for each 40 feet of the fall (maximum 20d6).

Extreme Gravity[edit]

Extreme gravity behave as heavy gravity, except it is much more hazardous, restrictive and heavy. Firstly the penalties increase to a -4 from a -2. Any objects or creature in heavy gravity has it increase by 300% to 1,000% of it normal gravity value. The DCs of any climb checks are quadrupled and it is impossible to jump in extreme gravity. At the start of each creature's turn it must make a DC 15 Strength check or be immobilized for 1 round, if the check fail three time consecutively the creature is also made prone.

Falling characters in an area of extreme gravity plane take 1d10 points of damage for each 5 feet of the fall (maximum 40d10).

Ranged Weapons and Gravity[edit]

It is no surprise that gravity has a large effect on ranged attack, especially projectile attacks. In light gravity, the effective range and range increment of projectile and thrown attacks is doubled, in low gravity the range increment do not change but the maximum range is doubled. In the case of no gravity projectile and thrown weapon have an essentially limitless maximum range (although atmospheric resistance might stop it eventually).

In heavy gravity the effect is reversed, both range increment and maximum range are halves. In extreme gravity the effect is dire, dividing both the range increment and maximum range by 5.

Gravity do not affect most rays, or the projectile from a Laser Gun. It exclude many spell attacks, although weighted projectiles are affected as normal. Since they do not have ranged increments, their range is simply modified by the gravity as follow: x2 (Light), x4 (Low and None), /2 (Heavy), /5 (Extreme).
