Does the 250k Wood Upgrades worth?

His numbers don't add up clearly. You can't invest wood into your guild, and at the rate I'm currently getting wood, I will always be able to climb further down in the mine without an issue. My axe is at 14, 3 dmg lower than 15, and I have 45.4667% dmg increase from my orbs. You get 0.058325% per level and at level 99 you don't even hit 53%. So if you need 58% to hit that magical 238 crit, somethings not right.
