Vermin Companions
System: Pathfinder | SRD | Type: animal_companion
Source: PZO1117
Vermin companions follow the same rules as animal companions, advancing their Hit Dice and other abilities per Table: Animal Companion Base Statistics. Vermin companions can be trained as if they were animals using the Handle Animal skill.
Mindless: Vermin companions have no Intelligence score and possess the mindless trait. In spite of this, vermin companions may learn one trick, plus additional bonus tricks as noted on Table: Animal Companion Base Statistics. If a vermin animal companion gains an ability score increase (at 4 Hit Dice, 8 Hit Dice, and so on), the druid can apply this increase to the companion’s Intelligence, changing it from — to 1, at which point the companion loses the mindless quality and is able to know up to 3 tricks per point of Intelligence, plus the additional bonus tricks, as per Handle Animal. Vermin companions have no skill points or feats as long as they have the mindless quality.
Trip: Because many vermin have multiple limbs, they are very difficult to trip. As a result, a CMD entry has been included for each, indicating the bonus to CMD such vermin receive against trip attacks.
