The official GemStone IV encyclopedia.
Duck and Weave is a combat maneuver available to rogues and monks that provides a 30 second boost to evade chance. The increase is higher when wearing lighter armor groups. When you evade an attack, there's a chance that you can redirect that attack against a different enemy. The redirection chance is higher in more offensive stances and is also based on influence and agility. Training in the Dodging and Multi Opponent Combat skills is recommended. There is a 5 minute cooldown period during which the reactivation cost triples to 90 stamina.
