On Earthquake power...possible spoilers....

Click to reveal..
I love my peeps and have put them through every experiment, experience and know all 90 by name and sight, I love this game! (as I have loved them all) BUT....
I have completed every aspect of the game I can see, over 90 pop, over 800 DE points, all totems, chief, got the GP Earthquake finally. Have tried it several places such as the camp (all heathen present)and the Circle. What does one do to convert the last red and orange masks? I saw one post that said it was done through the EarthQuake power. It takes so long to recharge, I hesitate to keep trying blindly. Having gone this far I don't want to quit, but just watching the over population run around and accomplish nothing for the last 5 days is not fun.


Just a hint, please???
