What are the various ways one can get a crystal?

1.Getting 20 power

2.Taking them from others

3.Voting 200 times

And how exactly is one's power rated? I'm sorry, I've just started playing as of a couple of days back ...

theres a bunch of things that calc power that power 20 thing is a one time thing you get to help you start for power
25 Workers = 1 power
10 soldiers = 1 power
1 conquer = 1 power
im not sure if any of that changed im pretty sure it hasn't

is that true? i thought ranged units got you more power than armor, which wouldn't happen if it was just unit count

im almost certain not 100% sure i'll look around until I find out check the Wiki and such

EDIT

"Power = (Workers / 100) + (Units / 10) + Conquers" -Quoted from http://guide.battledawn.com/index.php/Score_%26_Ranking I think the Wiki is way out of date OC perhaps?

EDIT again well this is interesting the Wiki is way off I just testes out on one of my worlds not even close as for the way I first said I should have 447 according to it but I have 67 so both are off as for the Wiki way it said I should have 19

I believe the new wiki, which is nearly finished is at: http://wiki.battledawn.com/

well according to that one my power should be (Workers / 25) + (Soldiers / 10) + Conquers what would be 66 so thats real close I still have 67 so its only one off

The numbers are rounded up, e.g., 11 soldiers gives you 2 power.
