Laceration boots
Laceration boots are tier 80 melee power boots. When worn, the boots allow the use of the Bladed Dive ability with any melee weapon equipped (as opposed to only dual-wield). This permits the use of Bladed Dive with only one mainhand melee weapon or a two-handed melee weapon equipped.
When used in conjunction with a halberd-class weapon, they allow the area of effect of Bladed Dive to be expanded to a 5x5 square. This can make Bladed Dive a very powerful ability for killing large groups of monsters with low lifepoints, as each target that dies within 6 seconds of using the ability will reset the cooldown, allowing the ability to be used repeatedly.
So in short this is best in slot Melee Boots if you utilize bladed dive or have it unlocked. It has the same stats as Torva Boots without the prayer bonus. If your not utilizing Blade dive Masterwrork boots is best in slot aswell
