Pickaxe Progression

To mine you will always need to have at least 1 Pickaxe. By owning a Miner, you will automatically have access to a Basic Pickaxe+9. This Pickaxe can only be used to mine in the Depths, the first cave. To mine more interesting items and recipes you will need a Pickaxe that can be crafted with the corresponding Recipe. The upgrade costs and success rate of the Pickaxe are:

Pickaxe Level	Upgrade Cost	Success Rate
+0	//	//
+1	250 Stone	100%
+2	400 Stone	95%
+3	1 Coal + 600 Stone	90%
+4	2 Coal + 800 Stone	85%
+5	3 Coal + 1000 Stone	80%
+6	4 Coal + 1 Iron Ore + 1200 Stone	75%
+7	5 Coal + 2 Iron Ore + 1400 Stone	65%
+8	1 Iron Ingot + 1700 Stone	50%
+9	1 Enchanted Stone + 2 Iron Ingot	40%

Once you have a Pickaxe +9 you can sacrifice it to craft a Common Pickaxe +0 that can be used to mine in the Underground Chasms with Better loot, better XP, and better recipes.
