Leap towards your specified location, spinning your blades around you as you land. Dealing 125% weapon damage to all enemies adjacent to or on-top of your specified tile. If any hit enemies die within 6 seconds of you hitting them, the cooldown of bladed dive gets reset.
Bladed Dive is a basic Attackability that can be bought from the Shattered Worlds reward shop for 63,000,000 shattered anima. It has a base ability damage of 25%-125%. This is the same base damage as Barge, another movement-based melee ability. Bladed Dive does not share a cooldown with any other ability. As with Barge and Surge, this ability is affected by the Mobile perk, bringing the cooldown and possible adrenaline gain down to 10 seconds and 0% respectively.
Bladed Dive may be used outside of the global cooldown; however, it will not deal any damage and no adrenaline will be gained (likely for balance reasons so that players don't get "free" adrenaline and damage every 20 seconds, or every time Bladed Dive is reset). Further, using Bladed Dive in this manner will not trigger Impatient.
Despite its low damage, Bladed Dive deals area of effect (AoE) damage within a 1 tile radius. In terms of overall damage however, two-handed melee abilities are still capable of significantly more damage against multiple targets. Therefore, the most likely uses of this ability are purely mobility-related, or to replace Slice in single-target situations, or to be used in-between two abilities as a result of being usable at nearly any time.
The ability will cause the player to leap towards the specified location, spinning the player's blades around them as they land, dealing damage to all nearby enemies. Choosing an attackable target instead of an empty tile will result in leaping next to the target, rather than on the same tile as the target.
A non-attackable NPC will give the following message: "You cannot attack that NPC." A feature (such as a Portable deposit box) will give the standard "Nothing interesting happens" message, even if the feature can normally be walked through.
Because hatchets and pickaxes are considered to be melee weapons, it is viable to equip one with an off-hand melee weapon with the Mobile perk, freeing up armour slots for skilling outfits. This will reduce the cooldown of Surge and Bladed Dive. Further, these two abilities can be used in tandem with each other to maximise speed while moving between skilling nodes, including reaching the Mage of Zamorak while crafting runes through the Abyss.
Bladed Dive currently suffers from the following bugs:
If used outside of the global cooldown, the ability's cooldown will not reset unless the target enemy was killed - other enemies killed are not considered.
The ability will not actually enter global cooldown, although the ability's icon will appear to indicate that it does. In conjunction with this, if other abilities are already on the global cooldown, their global cooldowns will not be refreshed by this ability.
Bladed Dive can be used while stunned. Because Kalphite King's "beetlejuice" (instant kill) attack stuns without binding, Bladed Dive can be used to escape it.
