In the end the cavemans were satisfied. But when they found a way to melt iron they recreated the upgrader. Now they are hopefully satisefied.. hopefully.

This upgrader upgrades the ore with 10% with an apply limit of 15. The effect limit is $100. This upgrader is sometimes used for starters content. It is the upgraded version of the Primitive Tack.

This upgrader can be upgraded to the Advanced Drop Tack.
