In the end the cavemans were satisfied. But when they found a way to melt iron they recreated the upgrader. Now they are hopefully satisfied.. hopefully.
The Drop Tack is a Regular Tier upgrader and the upgraded version of the Primitive Tack. It upgrades ores by 10% up to 15 times, totaling to 4.178x. It also has an effect limit of $100. This upgrader is sometimes used for starter content, but is outclassed by several other upgraders. It can be upgraded to the Advanced Drop Tack.
In extreme mode, it costs a bit more money as well as a handful of resources. It is also changed to be the upgraded version of the Primitive Tribal Upgrader rather than the Primitive Tack. Due to the cost, it is pretty much useless in money setups. In this mode, it can be upgraded to the Extreme Tack.
