PCs gain extra piety from sacrificing race-specific items like weapons for orcs, gold for dwarves etc. The bonus doesn't seem very significant though, especially for some races. For drakelings musical instruments are 'appreciated', but you don't find a lot of those, and for gray elves it's books and wands which you generally want to hold on to. I think the piety bonus should be somewhat adjusted for some races, and increased in general. This would make crowning less of a grind and more of a tradeoff (do I keep these potentially useful items or sacrifice them for a quicker crowning?)

edit: I accidentally made this into a bug report instead of feature, sorry for that.
