The fights in Lords & Knights are split into battlerounds with each round lasting 10 minutes. As long as there are at least 100 battle units on both sides, attackers and defenders, the casualties will not be more than 50 percent of the actual unit numbers. This does not mean, however, that the battle will definitely end in 1 round as soon as atleast 1 side has less than 100 battle units. If both sides are not strong enough to defeat all enemy troops in that round this battle will continue afterwards.

On battleworlds (depending on the server) 250 or 500 units are needed on each side for the battle to continue.

In fights for fortresses the required units are five times the standard number - 500 on normal worlds, 1250 / 2500 on battleworlds.
