Each of the companions that you come across in your journey, including Oliver have a favorite type of familiar. Just as everyone has a desire to delve a dark dungeon or slay a mighty beast, your companions have certain familiars that they just love to be around!

This love turns into a significant bonus in terms of fighting power. When the time comes, if your companions are using a favorite of theirs mid fight, you can expect that familiar to maintain a 10% bonus to their abilities.
