Attribute Modifiers
The Attribute Modifier Scales table shows some benchmarks for your creatures. Use high for the creature's best attribute modifiers, moderate for ones they're okay at, and low for the rest. If a creature has a truly bad ability, you can go as low as –5. That's the terrible range for attribute modifiers, and doesn't really change by level. This is most common with animals, which have an Intelligence modifier of –4 (for khefaks, laser wolves, rats, and such) or –5 (for more instinctual animals like insects), and for mindless creatures, which have a –5 Intelligence modifier.
Few creatures use the extreme column. A powerful, dedicated spellcaster might use an extreme spellcasting statistic, or a preternaturally charming creature like a nymph might have an extreme Charisma modifier. However, the most common way extreme numbers are used is for really big, really strong creatures. This happens with only Large or bigger creatures from 1st to 5th level, Huge or larger creatures from 6th to 9th level, and Gargantuan creatures from 10th to 15th level. Beyond that level, a creature doesn't gain an extreme Strength modifier from size alone.
