Catalyst

The Catalyst is a Minion Fuel item that increases minion resource generation by  for 3 hours, meaning it increases minion efficiency by. It triples the resources the minions would normally get from harvesting a block or a mob, therefore it doesn't actually have an impact on the time between actions. It is unlocked at.

It is one of the most well-known minion fuels as its main component, the Crystal Fragment, can be obtained by breaking the crystals that spawn when you fight the Ender Dragon in The End, occasionally by killing Zealots holding Ender Chests, or by fighting the Endstone Protector.

Catalysts are not bought off the Auction House, but rather the Bazaar. If you want to buy them off the Auction House, purchase Crystal Fragments, the main component of catalysts.

While not having an impact on the time between actions of a minion, Diamond Spreading will still apply to the extra drops gained from its bonus.

This can be upgraded to the Hyper Catalyst.
