Goal: When <minecraft:stone> breaks, replace all drops with <minecraft:string> * 100 AND <minecraft:diamond> * 10.

There are actually two ways that this can be accomplished. Both items could be defined as separate drops with the dropCount set to 2 and the dropStrategy set to UNIQUE. The other way, the way we will look at here, is to define both items in the same drop list and use the ALL drop list strategy. Drops defined using the second method will still only count as one drop with respect to the dropCount even if they drop more than one item.
