5.1. Planetary gravity field

The PC's native gravity field will affect characteristics involving basic body structure, etc.; and while a PC may adapt to gravity conditions considerably different from those of his planet of birth, he may labour under disadvantages at times.

Roll Effect of Native Planetary Gravity on Player Character

Modifier

1

PC is a native of a planetoid, orbital city, or IRSOL star city and has adapted to low and null gravity conditions. The gravity field is under 0.2 G. Low gravity favors development of a tall but slight frame. Gravity fields in the 1.0 G range or higher will prove to be quite uncomfortable, however much the PC has adapted to them. The PC will also have an automatic No. 1 or No. 2 result on the Planetary Atmosphere Table, as planets with 0.4 G or less will not retain atmosphere of breathable proportions. The likelihood is that the PC is expert in the use of auxiliary breathing apparatus and vacuum suits

The PC's Physique is +3, with a minimum 12 in size, but body mass will be only 90% of the normal value for his unmodified height.

2-3

PC is a native of a planet with a gravity field of 0.25 G to 0,4 G and has adapted to low gravity conditions. Gravity fields in the I.0 G range or higher will be rather uncomfortable. The PC will have an automatic No. l or No. 2 result on the Planetary Atmosphere Table, as planets with 0.4 G or less will not retain atmosphere of breathable proportions. The likelihood is that the PC is expert in the use of auxiliary breathing apparatus and vacuum suits.

The PC's Physique is +3, with a minimum 11 in size, but body mass will be only 90% of the normal value for his height

4-9

PC is a native of a planet with a gravity field of 0.5 G to 0.8 G and is somewhat adapted to tow gravity conditions.

The PC's Physique is +2, with a minimum 10 in size, but body mass will be only 95% of the normal value for his height.

10-16

PC is a native of a planet with a standard Terran' gravity field of 0.9 G to 1.1 G. If such an increase occurs, body mass will increase by 5-10% troll Id6) to represent heavier frame and musculature.

50% chance of increasing either his Strength or his Stamina (player choice) by +1 to reflecting the increased chance of development of physical power or endurance in a normal gravity field.

17-18

PC is a native of a planet with a gravity field of 1.2 to 1.4 G and is adapted to high gravity conditions. Strength and Stamina would naturally be improved under such arduous conditions. Agility would also be a factor for 'natural selection,' in that clumsy types would likely suffer from a fatal accident sooner or later, while coordinated persons would be better able to react quickly in e surface acceleration field significantly above the norm.

Physique -2 in size, but body mass will be 110% of the normal value for his height. Strength, Stamina, end Agility will be a minimum 11. There is a 100% chance that one of these three characteristics will be +1 (player choice) or a 50% chance that any two will be a 1.

19

PC is a native of a planet with a gravity field of 1.5 G to 1.B G end is very adapted to high gravity conditions. Very high gravity encourages heavy bone and muscle development, and also shorter height.

Physique -3 in size, but body mass will be 115% of the normal value for his height. Strength, Stamina, and Agility will be a minimum 12. There is a 100% chance that one of these three characteristics will be +1 (player choice) or a 50% chance that each of the other two will be a +1 as well.

20

PC is a native of a planet with a gravity field of 1.9 G to 2.5 G and is a superbly adapted heavy planet dweller.

Physique -4 in size, but body mass will be 120% of normal values for his unmodified height. Minimum Strength, Stamina, and Agility are 13. There is a 100% chance that two of these three characteristics will be +1 (player choice), and a 50% chance that the third characteristic is +1 as well.

If a personal characteristic is 'boosted' to a minimum value, the +1 bonus rule does not apply. For example, a PC from a No. 20 heavy planet has a Strength 9, which is boosted to 13 because of the high gravity environment. He does not have a chance at a further +1 Strength increase, as his physical development has already been corrected to correspond to environmental influences, If his Strength was 13, however, he could have an increase to 14,
