Countless hours of breaking space rocks and lots of collecting by other family members. Sadly, with all that tiberium, still no spire cuts for me. I'm not shore how you can cheat to get gems. I usually get 2-3 tiberiums per session at board breaker (she can't become fatigue due to supermaxed athletic too), and has steel bladder, plus moodlet manager, so only going to work is stopping her now, but soon she'll focus on just breaking boards.
