Server wars is an easy way to gain gems and resources, if you’re willing to spend some to begin with. The basics of Server Wars, if you kill an enemy troop, in your server or theirs, you’ll get points for it. Killing bosses and monsters in their server will also gain you points. During SvS, your hospital capacity is boosted by 50% and the first 100,000 troops that die can be revived in the hospital for little resources and after that, source of lives must be used to revive dead troops.
Alright, so you’ve got your ports ready and you need some targets, how’d you find them? There’s a simple method to do this. All you need to do is go to the server wars page, click on enemy rankings, navigate to alliances and view any alliances members. From there you’ll be able to see if there are any in your server. There will be an icon next to their avatar indicating that they’re in your server looking like this:
From this point you need to warrant them and when their bubble pops, or it might already be popped, you can attack.
This method is the best way for getting points as it’s in your server and you can bubble straight away after attack which you can’t do on the enemy server.
