Instantly brings you and the target next to each other, inflicting Ranged Physical Damage on the target while knocking the target back.

• Deals additional damage if the target hits a wall or an obstacle during the knockback.

• Consumes 1 Spirit Sphere till Level 5, at Level 6 and above no Spirit Sphere will be consumed.

Damage (ATK) = [Base_Damage × (BaseLv ÷ 100)]%

Added Damage (ATK) = [Base_Added_Dmg + (1000 × Target_CurrWeight ÷ Target_WeightLimit) + (Target_BaseLv × 5) × (BaseLv ÷ 150)]%

• Due to the circumstances of the sieges, the user will not be moved to the target's position and the Added Damage is always applied.
• Boss monsters will always take Added Damage.

• PvP builds may consider this skill for inflicting moderate damage and knocking back players. However, Gates of Hell inflicts more damage.
• Siege builds can benefit from the readily available Added Damage, allowing this skill to inflict high damage over time. Due to having no Cast Time and the possibility of using Magic Strings to reduce the Cast Delay, this skill can be cast rapidly from a long distance.

• In PvM, this skill does not show full damage from Added Damage regardless if the target has collided with an obstacle. This also applies to Boss monsters.
