I have deployed a small update improving the drop rates of Gemstones:
- mining 5 Iron Ore now has a chance of 20% to yield one Gemstone with an additional 10% chance to obtain another Gemstone
- mining 50 Iron Ore now always yields one Gemstone with a 50% chance to get 1-2 more
For clarification, this is how Gemstone rolls work:
On looting a completed timer that is eligible for Gemstones (Iron Ore/Bars) a roll will be made that will result in either none or one Gemstone according to the chances given above.
If that timer was for Iron Ore, *if* you got a Gemstone there'll be another roll to check if any extra Gemstone will be obtained. If that's the case you will get one extra Gemstone (5 Iron Ore) or 1-2 extra Gemstone (50 Iron Ore).
