Victory Points – or VP - are needed to move up in the DoT online leagues. You can gain VP from battles when raiding other players, or by capturing a land that generates VP points over time. Remember that you have to harvest VP from lands that generate it, just like you do with your Farm and Gold Mine.
But beware - if another player captures one of your lands or successfully attacks your city, they'll steal some of your VP, so make sure you keep your Kingdom is well defended. Your VP total will also decrease after a season has been calculated. So don't be sad when you lose your VP, it's normal and happens to all of us... a bit like having to breath, that's how normal it is.
