Suggestion - Waste Not Talent - Add iron ore to stone
The - Waste Not - Talent is kind of kind of not 100% useless but its also not really good Specially for 3 points. So why not give it a 5% 8% 10% chance to give me a small amount of iron ore when I'm mining stone. I could gain small amounts of ore without finding a cave early on to help start off. This would give the ability a huge new gain at same time keeping it balanced by the amount of mining to not be worth anything then a bonus.
