Benefit: You add +1 to the base weapon damage on all damage rolls you make using the selected type of Sunder weapon. Base damage improves along with weapon damage at each experience tier above courageous (i.e. at 6th, 11th, 16th, 21st, 26th, and 31st levels), meaning that this is a +7 bonus at 31st level and above. Base damage is always multiplied on a critical hit.
Special: All successful attacks you make with the chosen type of Sunder weapon, if it inflicts piercing damage, now also inflicts 5 points of Ruptured damage instead of Bleed.
