Well, the point is that you can get to neutral with Grox, that ain't really hard, afterwards getting to the center is a lot easier, 'coz you can stop on their own planets and repair/recharge, though it costs a lot more than with other aliens (They will still attack your ship, but they won't attack your colonies). And could anyone say, since the staff of life was already mentioned, is there a chance of recharging it?
