In the April 2002 event, "Betrayal", the Endurance attribute was given new functionality. If you had Melee Defense trained, you would have a chance to avoid losing any stamina when you successfully evaded a melee attack. The same was true for Missile Defense and missile attacks. This chance increased as your base Endurance increased.
We recently discovered a small bug in this system: it was possible to avoid losing stamina even if you did not have the proper Defense skill trained. This bug has been fixed in the December event.
This description is unfortunately not entirely accurate. The bug affected the stamina check on both evades and evasion failures.
What does this mean? It means that players who do not have the appropriate Defense skill trained may see increased stamina loss both when evading incoming attacks and being successfully struck by incoming attacks. <Link>
