The rules on sacrifice values seem to be poorly designed yet.
For instance, a weapon or piece of armor gives less than 500 points.
Meanwhile, a few apples (6) is worth ~1400.
Further, adding items like slingstones with 1 apple can given a lot of points (1 apple, plus 250 slingstones gave ~1500.)
The value of these extremely simple items added in is unbalanced, and at the least items should be much better in terms of value.
