Class Features
All of the following are class features of the Urban Druid.
Weapon and Armor Proficiency: A Urban Druid is proficient with club, crossbow (any), dagger, quarterstaff, rapier, sap, and short sword. They find armor to be distasteful and rude, and although they are proficient with padded, leather, and studded leather armor.
Spellcasting: An urban druid casts divine spells, which are drawn from the urban druid spells list. Her alignment may restrict her from casting certain spells opposed to her moral or ethical beliefs; see Chaotic, Evil, Good, and Lawful Spells, below. An urban druid must choose and prepare her spells in advance (see below).
To prepare or cast a spell, the urban druid must have a Charisma score equal to at least 10 + the spell level. The Difficulty Class for a saving throw against a druid's spell is 10 + Caster Level.
Like other spellcasters, an urban druid can cast only a certain number of spells of each spell level per day. She receives bonus spells per day if she has a high Charisma score. She does not have access to any domain spells or granted powers, as a cleric does.
An urban druid prepares and casts spells the way a cleric does, although she cannot lose a prepared spell to cast a cure spell in its place (but see Spontaneous Casting, below). An urban druid may prepare and cast any spell on the urban druid spell list, provided she can cast spells of that level, but she must choose which spells to prepare during her daily meditation.
An urban druid's divine focus is typically a manufactured or forged item common to a city, such as a gear, a tool, a horseshoe, or a similar item.
Spontaneous Casting: An urban druid can channel stored spell energy into repair spells that she hasn't prepared ahead of time. She can "lose" a prepared spell in order to cast any repair spell of the same level or lower.
Chaotic, Evil, Good, Lawful Spells: A druid can't cast spells of an alignment opposed to her own or her deity's (if she has one). Spells associated with particular alignments are indicated by the chaos, evil, good, and law descriptors in their spell descriptions.
City Sense Ex: An urban druid gains a +2 bonus on Gather Information and Knowledge (local) checks.
Favored City Ex: At 1st level, an urban druid must select a favored city. This must be a settlement of at least small town size or larger that the urban druid has visited, but need not be the city the urban druid currently calls home. As she gains levels, an urban druid may consider additional cities her favored cities.
While within the city limits of one of her favored cities, an urban druid gains a sacred bonus to all Bluff, Diplomacy, Gather Information, and Intimidate checks equal to her Wisdom modifier. In addition, she gains a +2 morale bonus on all Will saving throws.
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. As the urban druid advances in level, the companion's power increases as shown in that sidebar. An urban companion that improves as the urban druid gains levels adds Hit Dice appropriate to its type.
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 Druid's Animal Companion sidebar 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.
Crowdwalk Ex: At 2nd level, an urban druid can move through crowds with ease, moving as if in an open space. If an urban druid attempts to move through a square occupied by a hostile creature (such as with a Tumble check or an overrun attempt), she gains a +4 bonus on any skill check, Strength check, or attack roll made to resolve the movement.
Alley Fighting Ex: Urban druids are masters at fighting in cramped quarters, such as city alleyways or narrow dungeon corridors. At 3rd-level, an urban druid's ability to fight in these conditions improves greatly. As long as she is fighting in an area no wider than her space (5 feet for a Small or Medium humanoid), she gains a +1 competence bonus on all attack rolls. Additionally, if she makes a melee attack against a target around a corner, the target does not gain the benefit of cover (unless the foe has total cover). The urban druid retains the benefits of cover against her enemy, unless she is fighting another urban druid or other creature with a similar power.
Disease Immunity Ex: At 4th level, an urban druid becomes immune to all forms of disease, including supernatural diseases like mummy rot.
Urban Shape Su: At 5th-level, an urban druid gains the ability to turn herself into any Small or Medium urban creature. This ability functions identically to a druid's wild shape ability, save that the list of forms the urban druid can take is much more specialized: It is limited to creatures with the humanoid type or to any non-construct creatures from her urban companion list (see above).
An urban druid can use this ability more times per day at 6th, 7th, 10th, 14th, and 18th level. In addition, she gains the ability to take the shape of a Large creature at 8th level, a Tiny creature at 11th level, and a Huge creature at 15th level. The new form's Hit Dice can't exceed the character's urban druid level.
At 12th level, the urban druid becomes able to use urban shape to change into an object (size based on the sizes allowed by the urban shape ability), such as a door or a wagon. The urban druid gains hardness equal to the material assumed, but the urban druid cannot assume the form of an object with a hardness of more than 10. As long as the urban druid is in object form, she has no means of locomotion or speech, but she retains awareness of her surroundings as if she were in her natural form.
At 16th level, an urban druid becomes able to use urban shape to transform into a Small, Medium, Large, or Huge animated object once per day. These construct forms are in addition to her normal urban shape usage. In addition to the normal effects of urban shape, the urban druid also gains all of the animated object's extraordinary special attacks and special qualities, including any defenses gained from the construct type. Her type changes to construct for the duration of the animated object form. A urban druid who becomes an animated object has no Constitution score for as long as he remains an animated object. The urban druid gains bonus hit points based on his size while an animated object, as usual for a construct.
At 18th level, an urban druid gains the ability to assume animated object form twice per day, and at 20th level she can do so three times per day. At 20th level, she may use this ability to change into a gargantuan animated object.
Information Network Ex: Upon reaching 9th level, an urban druid has established an information network in a number of cities equal to her Charisma bonus. While in any of these cities, the urban druid only takes half an hour to make a Gather Information check (rather than a full evening or day). In addition, if any event occurs in a city that would interest the urban druid, she may make a Gather Information check to learn of the event as a free action. Knowledge of such an event reaches the urban druid's ears in 1d4 hours unless the urban druid is in an area that cannot be reached by her contacts.
