The following buttons all roll from the same loot table, but simulate generating depending on the looters axe level.

There is a single loot table that inherits from 3 different loot tables: Stones, Metals, Gems.

Stones just has 1 entry: stone

Metals just has 3 entries: gold, silver and bronze. To mine gold you must be axe level 4+, silver 3+ and bronze 2+.

Gems has 2 pools, one for diamonds and one for diamonds, rubies and sapphires. Diamonds require level 5+, ruby 4+ and sapphire 2+.

The gems table has lots of conditions, utilising the dependLooter default condition.

We highly encourage you to check out the source code to see how it works.
