Just an FYI, I'm not sure if this is intentional, but the right click for the dual wield weapons has no cool-down and allows the user to gain DPS based on the amount of times they can click. This means with even an average cps, spamming the secondary weapon allows you to reach ungodly amounts of damage and I cannot even imagine what is possible with an auto-clicker.

Due to the various issues, Dual Wield items have now been moved to Experimental, pending a complete reimplementation. Experimental will be added in the next beta release.
