Size

There're 7 core Sizes that are each double that of the previous size. While you shouldn't obsess over exact measurements, you can use the units listed below as a reference.

The game will use Size to describe creatures, objects, and areas of effect for Abilities.

Creatures of a given Size may not take up that full cube of space, but they do take up enough of the space that only creatures more than one size larger or smaller than them can get by.

Creatures that don't neatly fit into their cube may also list a modifier after their size. Size Modifiers won't provide an exact size, but they hint at how much extra or less space they take up. The modifiers are as follows:

Size Modifier Modification Description
Short Height is closer to half their cube size, or shorter.
Tall Height is closer to one and a half their cube size, or taller.
Long Length is closer to double their cube size, or longer.
Below are some examples of creatures for different modified sizes:

Size Modifiers are there for the GM to reference and use when making calls, but have no explicit mechanical bearing on the game like the base Sizes do.
