I'd like to take a moment and point out the spokesman for the Plunder War Noob Generation. He is the OP, and he loves you all.
If you need them, they will automatically add the specific bonus to your stats each time someone attacks you.
no offense but not just a Nooblet also not that bright if the name didn't say it all to you Hun, Defensive potions- when attacked your kingdom will automatically pick the right potion(s) to help defend your kingdom. Your kingdom will only use 1 of each potion you own and only the ones you need to win Eg: if you own all the potions but only need 1 to work they will only take the 1 you need, if you need all to work they will take all. you may still lose because your opponent may either have a lot of good stat allies helping them or they used attack potions
How the hell do you NOT know how defense pots work when you're 2mil combined? Either you've spent a ton of cash on nobility or you've PW-ed 24/7 and have never been on forums apart from now.
