Shocking a Creature will increase its Efficiency. While the Creature may perform tasks at an improved rate, Shocking will deplete their Happiness. Reduced Happiness will cause a Creature to go on Strike.
The ability to Shock a Creature is available after Researching the Forced Labor Technology. The Technology Merciless Labor increases the effect of Shocking from 5% to 10%.
To Shock a Creature, locate them in the Dungeon, then Click on their animation. This will bring up the option to Select the Creature. The player will then be presented with information and options for that Creature. Selecting Shock will increase their Efficiency. This can be done enough times to increase the Creature's Efficiency to 200%.
Players must balance this mechanic to make a Creature more Efficient, while not causing their Happiness to be reduced too greatly.
