Ability Bonus: +2 to Constitution, +2 Wisdom, -2 Charisma
Favored Class (Slayer): Dwarves can choose any one class as their favored class at 1st level. Once made, this choice cannot be changed.
Defensive Training: Dwarves gain a +4 dodge bonus to AC against monsters of the giant subtype.
Hardy: Dwarves gain a +2 racial bonus on saving throws against poison, spells, and spell-like abilities.
Stability: Dwarves gain a +4 racial bonus to their Combat Maneuver Defense when resisting a bull rush or trip attempt while standing on the ground.
Lorekeeper: Dwarves keep extensive records about their history and the world around them. Dwarves with this racial trait receive a +2 racial bonus on Knowledge (history) checks that pertain to dwarves or their enemies. They can make such skill checks untrained. This racial trait replaces greed.
Stonecunning: Dwarves gain a +2 bonus on Perception checks to notice unusual stonework, such as traps and hidden doors located in stone walls or floors. They receive a check to notice such features whenever they pass within 10 feet of them, whether or not they are actively looking.
Darkvision: Dwarves can see perfectly in the dark up to 60 feet.
Giant Hunter: Dwarves with this racial trait gain a +1 bonus on attack rolls against humanoids with the giant subtype. Furthermore, they gain a +2 bonus on Survival checks to find and follow tracks made by humanoids with the giant subtype. This racial trait replaces the hatred racial trait.
Weapon Familiarity: Dwarves are proficient with battleaxes, heavy picks, and warhammers, and treat any weapon with the word “dwarven” in its name as a martial weapon.
Studied Target (Ex): A slayer can study an opponent he can see as a move action. The slayer then gains a +1 bonus on Bluff, Knowledge, Perception, Sense Motive, and Survival checks attempted against that opponent, and a +1 bonus on weapon attack and damage rolls against it. The DCs of slayer class abilities against that opponent increase by 1. A slayer can only maintain these bonuses against one opponent at a time; these bonuses remain in effect until either the opponent is dead or the slayer studies a new target.
If a slayer deals sneak attack damage to a target, he can study that target as an immediate action, allowing him to apply his studied target bonuses against that target (including to the normal weapon damage roll).
Track (Ex): A slayer adds 1/2 his level (minimum 1) to Survival skill checks made to follow tracks.
