It's a passive skill, which means it's always activated and doesn't use mana. It will allow the Vampire to use both her weapons to block and parry incoming attacks, effectively replacing the need of a shield. Weapon Block is added protection on top of defense.As it has steep diminishing returns, significant investment in this skill will achieve less and less benefit. Be sure to always have Burst of Speed activated for its speed advantage. At the first level, this skill can last up to two minutes (and more with additional points). It's also great for moving around very quickly, making traversing across land a lot faster, as well as being able to outrun enemies. This allows the player to heal as fast as they take damage. It will increase attack speed, which will allow building up charges faster and release them faster. Burst of Speed is fantastic for the Vampire.

It will make the small and light claw-class weapons extremely powerful in the hands of one with adept skill in Claw Mastery. Claw Mastery is important for increased attack rating, damage, and chances for critical attacks.

The exception being unleechable opponents like skeletons.

Energy: Usually left at base as skills are not very mana intensive and most of the time, Cobra Strike will refill the mana pool quickly.

Vitality: Typically, the rest of the stat points.

Dexterity: High enough to equip desired weapons or, if a player is using a shield, to raise block to 75%.

Strength: High enough to equip desired equipment.
