Mountain Strategy Feat 1Dwarf Source Player Core pg. 44 2.0
Dwarves have a long history fighting common foes, and you've mastered the ancient tactics to better face these enemies. You gain a +1 circumstance bonus to damage with weapons and unarmed attacks against creatures with the
giant,
goblin,
hryngar, or
orc trait. If your attack would deal more than one weapon die of damage (as is common at higher levels than 1st), the bonus is equal to the number of weapon dice or unarmed attack dice.
In addition, if any creature critically succeeds at an attack against you and deals damage to you, you gain your bonus to damage against that creature for 1 minute regardless of whether it has the chosen trait.
Special Your GM can add appropriate creature traits to the ancestral foes list if your character is from a community that commonly fights other types of enemies.
