Dominations Game Barbed Wire Trap
The Dominations game barbed wire trap is an AOE (Area of Effect) trap which slows attacking soldiers by 45% and reduces damage by 40%.
Place the barbed wire traps near walls which the enemy must break to destroy your town center and basically increase your walls HP by 40%.
Note now many (x3) sabotage tactics this attacker had to use to keep their 20 high level cavalry alive just to destroy the town center. Without the barbed wire effect they wouldn't have needed any sabotage tactics for a quick town center win.
One of my barbed wire traps had already been set off in an earlier attack by someone who force quit the game, presumably they lost all their attacking troops :-)
If you can position your 3 barbed wire traps around the town center and near to walls the enemy must pass through to destroy the town center, will reduce their damaging impact by 40% in that key area giving your defense time to destroy them or at least stop them destroying your entire town.
