I do this all the time. The trick is to use the least powerful attacks on your target. Sword has the 2&3 shot that do very lil damage and if you get it in rotation, you can jsut keep doing it when it recharges in between other weapons. Gun the Skelly shot works great on living things for max reps and living shot on skellys for max. Doll, chain and curse (scortch too if you didnt skill it up alot). Dagger is alot of throw dirt (or 1&2 if you have a higher lvl enemy). Nades is smoke bombs. Staff, Banish on living. Using all weapons with one crew, you can get 720 reps.
Ive gotten 600 reps on one stump, only cause my Nades were already mastered.
