Also, the problem is that not every character, based on their role-playing, will take someone else's loot. But opponents, as a rule, don't hesitate to take yours. As a result, the expected value sharply decreases if you role-play consistently. Or you have to come up with some not entirely reasonable pretexts to take someone else's loot.
Regarding the intermediate reward: well, there used to be various stat bonuses and that was fine. Well, I don't know how it is here, but a small monetary reward is probably acceptable (although there will be some problems with justifying such a reward). Or bets, as it was last time... In general, I wouldn't say that I see a serious problem here. /
