[QUOTE="Matthias, post: 6013398, member: 3625"] I forgot about gravity--that's another good one. I can't recollect Dragonstar's rules for variant gravity but if I had to improvise some quick pre-game rules from scratch they would look like this. [sblock]Note: These rules are not meant to serve as a scientific treatise but are only meant to simulate the effects of gravity well enough to allow suspension of disbelief for the layman player. If you want to try to calculate how much momentum shooting an arrow will give a creature in a zero-g environment, don't let me try to discourage you, but bear in mind all the factors that would have to go into a realistic version of such a calculation--you would have to calculate average values for the mass the arrow, the power efficiency of the bow, wind resistance effects, and the average mass of a player character (and if you wanted to have monsters and NPCs perform the same stunt, they come in an even greater range of masses, because a Huge creature would gain less from a bowshot than a Small one.[/sblock] GRAVITY LEVELS--DEFINITIONS Gravity environments range in strength from 0 to 10. A gravity level of 0 denotes the absence of gravity. Gravity in the range of 1 to 3 is considered "microgravity". Gravity of strength 4 to 6 is considered "normal" and imposes few penalties on creatures acclimated to life on a conventional planetary surface. Gravity of a strength from 7 to 9 is found on super-Earths, in the deep atmospheres of gas giants, and in high acceleration environments (such as experienced by fighter pilots) and represent the limits of survivability for mortal creatures. Gravity strength 10 represents any extreme light-bending gravity field generated by such objects as neutron stars, black holes, Spheres of Annihilation, and Implosion spells. Gravity Strength Table [sblock]0 Zero (0 g) a.k.a. freefall 1 Nil (1/10 g or less) 2 Faint (1/4 g) 3 Light (1/2 g) 4 Light Normal (4/5 g) 5 Normal (1 g) 6 Heavy Normal (1 1/5 g) 7 Heavy (1 1/2 g) 8 Severe (3 g) 9 Crushing (9 g or more) 10 Relativistic gravity [/sblock] Antigravity, where it exists, would be represented by a negative number of the same magnitude as a normal gravity field of equal strength. MOVEMENT Normal overland movement in a gravity environment of 3 or less requires making a Climb, Swim, Acrobatics, or Fly check* for those not acclimated to the variant gravity or untrained in moving around in it. If a creature is physically incapable of performing any of these (for example, being in free fall in vacuum with no solid surfaces in reach), they gain the free-floating condition (lose dodge bonuses and Dexterity to AC and Reflex saves, move actions are limited to worn/carried equipment)? *Free-floating movement in a freefall environment [sblock]In freefall, Fly checks can be made through the use of worn/carried equipment. For example, throwing a rock, shooting an arrow, or discharging a firearm in a certain direction will cause you to move very slightly in the opposite direction. Objects and rates of movement are as follows. Throwing a minor object (anything with a weight of "—"): 5 ft per object thrown, per hour Throwing an object of less than 10 lb.: 5 ft per minute Throwing an object of 10 lb or more: 25 ft per minute (5 ft in 2 rounds) Shooting a bow, crossbow, or similar hand-drawn weapon: 50 ft per shot, per minute (5 ft per round) Discharging a personal firearm or firing a ballista: 500 ft per shot, per minute (50 ft per round) Note that one can throw/shoot/fire multiple objects to increase one's speed in a given direction, or reduce it (by aiming in the direction of movement). If a creature in freefall needs to propel himself toward a specific point (such as the door of an airlock or toward another creature or a weapon in freefall), he must make a Wisdom check to accurately propel himself in the appropriate direction; DC is equal to object's touch AC +2 per 10 feet of distance. If the creature fails the Wisdom check, he will miss the target's square by 5 feet per point missed. [/sblock] RESILIENCE Variant gravity can have an influence on how far a creature can run, swim, or perform other stressing manual labor before it becomes fatigued or exhausted.
