Lifecoil Engine

Lifelink

both own and control Lifecoil Engine and a

then meld them into CoilEngine Wurm
"Surely even the Queen herself will be impressed by
this machine. Able to gobble hordes all day long and
harvest the geists produced. I've almost perfected a
means that will allow them to combine for more
strength."- Maniac Assembler 6/6
