Laguna Blade
A simple spell that deals extremely high damage to a single target, Laguna Blade is a powerful fixture in Lina Inverse’s arsenal. This spell will be the source of many of your kills for a large portion of the game.

Level 1 - Deals 450 damage. (338 with hero reduction) 2 minute 30 seconds cooldown(!!). 280 mana cost.
Level 2 - Deals 675 damage. (506 with reduction) 1 minute 30 seconds cooldown. 420 mana cost.
