On peaceful survival, my land is 164, my power is 109, and my maxpower is 200. I cant claim land because my power isnt up to the maxpower. How do I use all of my power up to my maxpower?
You have 200 maxpower, 109 power, that means that other players have died in your faction and that drags the power down. If the player stays online for a certain amount of time after they died (Lost power) then they will gain their power back. The only way to use your max power is to have everyone in your faction stay at 10 power. Right now if you wanted more land you'd have to wait till your power is at 165 to claim 1 more piece of land.
Inactive people get kicked over time but even if you have 10000/10 power you still can't get overclaimed
