There should be different types of rook in an attack. One could grab a glitch and fly off and the glitch would have to do work for the rook. Another could break a street and it would take healing with 7 glitches at a meditation orb(new skill) to get it back and there would be nothing but patches where trees used to grow. In the comments you can come up with other types. The rooks would come in some type of order with the average first and the street destroyer last.(all rook share the health on top).
