The Black Slayers from Sliverthorn and A Darkness at Sethanon by Raymond E. Feist. They get stronger with each person they kill and can even heal themselves to a certain extent once they've killed enough: one had his right arm almost completely broken but after killing a few more guards the arm repaired itself. Also Murmandamus and Leso Varen, two very powerful necromancers in Feist's universe, have this power by killing people and capturing their residual life-force to use it for various purposes (power augmentation, enhanced condition, and semi-immortality to name a few).
