crossed swords icon

i’m new to this game and have a lot to learn.  i’ve noticed that all the ‘player’s lists’ have “crossed swords” to the right of their names.  i’m past level 20 and have just one sword - did i miss something?  i seem to be the only player to not have crossed swords!!  any help appreciated!

it’s just to indicate who you are. You will not ever show as crossed swords, as far as I understand having been playing for 5 months.

Two crossed swords mean that you can fight that specific player, 1 single sword mean that you  test a base (that can be yours or of a member of your alliance).

Test defence is totally free in terms of gems/pearls, instead in a real fighting you have to be careful on what you click because there you can spend them to cast Scrolls !
