Abh mod/Gravity Generator
The Gravity Generator was introduced in 0.5.3RC1.
The gravity generator is a buffing part which buffs gravity powered parts: tractor beams, (Star Trek) shields, gravity drives, gravity and shield wave weapons. IF its health reaches a critical level of 35% or less it will automatically switch to shield mode to protect itself and surrounding parts. In this mode it will stop buffing. Its shield is extremely weak.
Simply place it adjacent to the parts to be buffed. No extra care is needed.
