Urban Companion (Ex): An urban druid begins play with an urban companion selected from the following list: Small animated object, bat, dire rat, rat, cat, dog, riding dog, horse (light or heavy), Medium monstrous centipede, Small monstrous scorpion, Small monstrous spider, mule, owl, pony, raven, snake (Small or Medium viper), warhorse (light).
This creature is a loyal companion that accompanies the urban druid on her adventures as appropriate for its kind. A vermin serving as an urban companion has an Intelligence of 1, and its type changes to animal.
A 1st-level urban druid's companion is completely typical for its kind except as noted in the Druid's Animal Companion sidebar on page 36 of the Player's Handbook. As the urban druid advances in level, the companion's power increases as shown in that sidebar.
If an urban druid releases her companion from service, she may gain a new one by performing a ceremony requiring 24 uninterrupted hours of prayer. This ceremony can also replace a companion that has perished.
An urban druid of 4th level or higher may select from alternative lists of creatures (see below). Should she select an urban companion from one of these alternative lists, the creature gains abilities as if the character's urban druid level were lower than it actually is. Subtract the value indicated in the appropriate list header from the character's urban druid level and compare the result with the urban druid level entry on the table in the sidebar on page 36 of the Player's Handbook to determine the companion's powers. (If this adjustment would reduce the urban druid's effective level to 0 or lower, she can't have that creature as a companion.)
Any construct that serves an urban druid is spontaneously created by the 24-hour prayer that calls the urban companion; the urban druid need not have the Craft Construct feat or expend gold and experience points to gain the construct companion.
