Instead of an animal, you bond with a monstrous spider.
Prerequisite: Vermin Trainer, animal companion
Benefit: You can select a monstrous spider as your animal companion. This spider gains all the benefits normally granted to animal companions.
At 1st level, you can select a Tiny, Small, or Medium monstrous spider as your spider companion. A druid of sufficiently high level can select a more powerful creature as her spider companion, applying the indicated adjustment to the druid's level (in parentheses) for the purpose of determining the spider companion's characteristics and special abilities.
| Spider | Minimum Level (Adjustment) |
| Large | 4th (-3) |
| Huge | 10th (-9) |
Normal: Spiders are not available as animal companions.
