Waste Not (3.5e Flaw)
From D&D Wiki
All these effects apply to all beasts and humanoids with non rotten flesh. Zombies, incorporeals, elementals, and similar entities do not activate this flaw.
Waste not can be avoided by distancing oneself by at least 60ft away from a flaw activating corpse, by successfully salvaging one (of a possible many) corpses with a profession: (hunter) skill check, or by effectively destroying the body so that it is not longer salvageable. Disengaging line of sight does not deactivate this flaw on its own.
Salvaging a body with a profession: (hunter) skill check takes 10 minutes, or 5 minutes if rushed (-15 penalty), and it has a DC of 15. Failing a salvage check effectively destroys the body.
Upon successfully making the check, this flaw can not be activated for 12 hours.
The effects of Waste Not apply significantly during multiple-enemy combat situations. Once one enemy or ally has fallen, the presence of their dying body or corpse causes Waste Not to activate. As for combat against a single enemy, once the flaw is activated by felling the opponent, the danger is passed and being shaken will matter much less.
