Boots of Lightning Speed

Boots of Lightning Speed are a pairs of boots that boost your normal moment speed by 4, at the cost of unable to attack or cast spells. They're obtained by killing Habib.

Note you may still use innate ability, sequence spells, or other class abilities such as hide in shadows. Subsequent haste effects will boost the speed further.

In-game description
"These modified boots of speed were originally intended to boost the wearer's speed rating to even greater rates: They make the wearer as fast as if a Haste spell had been cast upon someone wearing normal boots of speed. Unfortunately, the wearer cannot attack, and the strain of rushing around so fast quickly tires even the most stalwart of heroes. Their nickname is "Heel of the Coward," for that summarizes their most obvious use: running away."
