Darkvision
Cornered Fury: Ratfolk can fight viciously when cut off from friends and allies. Whenever a ratfolk with this racial trait is reduced to half or fewer of his hit points, and has no conscious ally within 30 feet, he gains a +2 racial bonus on melee attack rolls and to Armor Class. This racial trait replaces swarming.
Unnatural: Some ratfolk unnerve normal animals, and train to defend themselves against the inevitable attacks from such creatures. These ratfolk take a –4 penalty on all Charisma-based skill checks to affect creatures of the animal type, and receive a +2 dodge bonus to AC against animals. An animal's starting attitude toward ratfolk is one step worse than normal. This racial trait replaces rodent empathy.
Throw Anything
Martial Weapon Proficiency (Longbow)
Alchemical Weapon (Su)
At 2nd level, a grenadier can infuse a weapon or piece of ammunition with a single harmful alchemical liquid or powder, such as alchemist’s fire or sneezing powder, as a move action. This action consumes the alchemical item, but transfers its effect to the weapon in question.
The alchemical item takes full effect on the next creature struck by the weapon, but does not splash, spread, or otherwise affect additional targets. Any extra damage added is treated like bonus dice of damage, and is not doubled on a critical hit. The alchemical treatment causes no harm to the weapon treated, and wears off 1 minute after application if no blow is struck. At 6th level, a grenadier can use her alchemical weapon ability as a swift action. At 15th level, this ability becomes a free action.
Precise Bomb: Whenever the alchemist throws a bomb, he can select a number of squares equal to his Intelligence modifier that are not affected by the splash damage from his bombs. If the bomb misses, this discovery has no effect.
Explosive Bomb: The alchemist’s bombs now have a splash radius of 10 feet rather than 5 feet (see Throw Splash Weapon). Creatures that take a direct hit from an explosive bomb catch fire, taking 1d6 points of fire damage each round until the fire is extinguished. Extinguishing the flames is a full-round action that requires a Reflex save. Rolling on the ground provides the target with a +2 to the save. Dousing the target with at least 2 gallons of water automatically extinguishes the flames.
Bomb: 7/day
Mutagen: (Standard choice) +2 Natural armor, +4 Dex, -4 Wis. 20 minute duration.
[Note: +4 total AC, +2 Ref, +2 ranged attacks, -2 Will.]
