Universal Creature Rules as Special Abilities

Source Alien Archive pg. 142
Universal creature rules can be used as a special abilities; these rules can be found in Appendix 4, starting on page 152. Some of these require you to determine the parameters of the ability. For instance, if you give a creature a breath weapon, you need to pick its size, damage type, and frequency. Such abilities often have a Guidelines entry to assist you.

Special abilities that only adjust a NPC’s basic statistics aren’t listed in the creature’s stat block; their effects are simply calculated into the statistics.
