 oc:tooltip.Acid=Eine hochgiftige Möchtegernflüssigkeit, wird üblicherweise nur von gewissen Piraten konsumiert. Dank ihrer korrosiven Eigenschaften ideal zum Bedrucken von Leiterplatten geeignet.
 oc:tooltip.Adapter=Erlaubt es Blöcke anzusteuern, die keine Komponentenblöcke sind, wie etwa reguläre Minecraft-Blöcke oder Blöcke anderer Mods.
 oc:tooltip.ALU=Zählt Zahlen zum Zeitvertreib. Klingt komisch, is aber so.

 oc:tooltip.Acid=A highly toxic pseudo-liquid, usually only consumed by certain pirates. Thanks to its corrosive nature it is perfectly suited for etching circuit boards.
 oc:tooltip.Adapter=Used to control non-component blocks, such as vanilla blocks or blocks from other mods.
 oc:tooltip.ALU=Adds number so you don't have to. It might be better this way.
