In I&A creatures are considered as physical beings that take up space, and to represent that space, every
creature has a Size, represented via different categories. These categories, each explained in greater
detail below, will indicate the size of a creature relative to other creatures, the amount of space it
takes up, its Base Speed, its Dodge Penalty, its R-DEF, the amount of fall damage that it takes, and its
carrying capacity is affected.
Space. The amount of "physical" space a creature occupies or otherwise has control over. See
Part 6 - Adventuring: Actions for the rules concerning moving through
other creatures' space.
Base Speed. How fast a bipedal creature moves when its AGI is 0; if it is an aquatic or winged
creature, then this number applies to its swimming or flying speed, respectively. A creature with
>4 legs gains another 2m/sec to its Base Speed.
Dodge Penalty. The penalty a creature takes when calculating its Dodge score; subtract this value
from the sum of the creature's AGI and DEX scores unless otherwise stated by a special exception, such as
the Practiced Dodge classless feat.
R-DEF. How a creature's M-DEF is modified to account for non-melee attacks; see
Defenses for more information.
Fall Damage. The amount of damage a creature takes for every 3m that it falls, not reduced by
anything; see Part 6: Adventuring - Advanced Combat for more
information.
Carrying Capacity. The amount of weight a creature can carry before becoming encumbered; see
Ability Scores (STR) for more information.
Weapon Size
A creature's Size also determines what weapons it is able to wield: essentially, a creature can wield a
weapon designed to be wielded by creatures of a single Size larger than itself using both hands, e.g. a
Small creature could wield a regular sword as a two-handed weapon, but it could not wield a greatsword;
alternatively, creatures can wield weapons designed for creatures up to two Sizes smaller than them
without issue, e.g. a Big creature can wield Large, Medium, and Small weapons without difficulty or hindrance.
A Tiny creature takes up practically no area whatsoever and can almost certainly be ignored
unless it is an active threat. Tiny creatures are also special in that they can occupy the
space of another creature without requiring a special exception to do so. Examples include
cats, Imps, and insects. Space: .5 x .5 meters Base Speed: 1m/sec Dodge Penalty: -0 R-DEF: M-DEF +6 Fall Damage: 1d2 per 3m fallen Carry Capacity (Minimum): STR times 10 (3 lbs)
Small, Medium, and Big encompasses all Sentients and most all Beasts and
natural creatures in I&A. Examples include Human children (Small), Wolves
(Medium), and Orks (Big).
Small Sentients gain .5 to their DEX score, but lose .5 to their STR
score; Big Sentients, on the other hand, gain .5 to their STR but lose
.5 in their DEX - these changes cannot go above 5 or below 0.
The following is formatted as [Small]/[Medium]/[Big]. Space: 1 x 1 meter Base Speed: 2.5/3/3.5m/sec Dodge Penalty: -2.5/-3/-3.5 R-DEF: M-DEF +3.5/+3/+2.5 Fall Damage: 1d4 per 3m fallen Carry Capacity (Minimum): STR times 50 (15 lbs)
Large creatures are about twice the size of Medium ones, and many Monstrosities
and larger Beasts fit within this category. Examples include Ogres, Cockatri, and Phoenixes. Space: 2-3 x 2-3 meters Base Speed: 4m/sec Dodge Penalty: -4 R-DEF: M-DEF +1 Fall Damage: 1d6 per 3m fallen Carry Capacity (Minimum): STR times 100 (25 lbs)
Huge creatures are giant monsters that hulk over almost everything in their path and
can kill most things in a single hit – or more frequently, a single bite. Examples include
Cyclops, Basilisks, and Dire Wolves. Space: 4-5 x 4-5 meters Base Speed: 5m/sec Dodge Penalty: -5 R-DEF: M-DEF +1 Fall Damage: 1d8 per 3m fallen Carry Capacity (Minimum): STR times 150 (40 lbs)
The penultimate Massive is gargantuan, representing creatures so huge even experienced
adventurers would rather flee than face such a terror. Examples include Hydras, T-Rexes,
and Quetzalcoatls. Space: 6-7 x 6-7 meters Base Speed: 6m/sec Dodge Penalty: -6 R-DEF: M-DEF +1 Fall Damage: 1d10 per 3m fallen Carry Capacity (Minimum): STR times 200 (50 lbs)
Lastly, we get to the biggest possible size categorization: Colossal. Colossal creatures
are massive, titanic behemoths that, although terrifying based on their size alone, are usually
extremely easy to hit, though their Armor scores may still negate any damage dealt to them.
Examples include Krakens, Elder Dragons, and Behemoths. Space: 8+ x 8+ meters Base Speed: 7m/sec Dodge Penalty: -7 R-DEF: M-DEF +1 Fall Damage: 1d12 per 3m fallen Carry Capacity (Minimum): STR times 250 (75 lbs)
