I'm thinking of making a black blooded oracle with the blood spurt feat (https://www.d20pfsrd.com/feats/combat-feats/blood-spurt-combat/) so i can spurt black blood at enemies at will, but I have a hard time finding special abilites that inflict bleed damage to self trigger the feat.
Would bleeding wounds (su) from the oracle bones mystic work? (https://www.d20pfsrd.com/classes/base-classes/oracle/mysteries/paizo-oracl e-mysteries/bones/)
It'd work IMO, but it might require you to use up a 1st level spell slot each time. A bloodletting kukri would work without using any such resources, or a robe of needles is dirt cheap and could be used at least six times a day without using any resources of your own.
Then there is the Extraction Scarificator for 2,500 gp. 1/day use it to do some damage, including some bleed damage. It leaves you bleeding, but then gives you a potion from it's use. [potion of lesser restoration, cure moderate wounds, calm emotions, or rage.] Does need at least two rounds to collect enough to generate the potion, so might not be in combat usable. Preparing for combat, however....
