if the player accepts the challenge. Supports will be withdrawn from both players automatically. The fight continues until one of both players clicks "end duel" - usually the losing person will probably do it

after the end of the duel, the player cannot receive support for 2 days - so that someone did not send attacks.

someone will finish the duel an hour before he comes and keep the castles at use support other players.

in this way players who want to fight could do it without confusing players who don't want to fight.

in the past, no one wanted to fight someone one on one. because no one trusted the other that he would not receive the support of other players.
