Finding and Trapping a Charged Creeper
Charged creepers spawn naturally during thunderstorms or when lightning strikes near regular creepers. Build or place a 
Capture Trap block in an open area where lightning can strike. When a charged creeper approaches or spawns nearby, it will be drawn to the trap.
Converting to a Keeper
Once trapped on a chip, expose the creeper to lightning again. You can do this by:
- Waiting for another thunderstorm to pass over the trapped creeper
- Using a lightning rod or similar mechanism to channel strikes toward it
- Positioning the trap in an exposed location during storms
When lightning hits the trapped charged creeper, it transforms into a Cyborg Keeper. The keeper will now:
- Actively hunt hostile mobs around your base
- Generate power to fuel your Sentry Turrets
- Remain loyal and won't attack you or peaceful mobs
Placement Tips
Keep your Keeper near your turrets for optimal power supply. You can display it on a chip mounted anywhere in your base, and it will continue defending and powering nearby defenses.
