Lina

Lina is an Intelligence caster Hero, adept at destroying enemy heroes fast and delivering massive bursts of magical damage, making her one of the most effective early gankers. Though her fiery power decreases in the later stages, her spell damage is nevertheless, still powerful enough to kill a single hero. Everytime she casts a spell, her speed, both attack and movement is enhanced to a higher level, allowing her to inflict more damage using her normal attacks.

Lina has the most powerful nuke spells in the game and can work as a powerful auto attacker thanks to her skillset. However, with high offensive power, comes naturally low defense, and she is one of the more fragile heroes. She is recommended for beginners to intermediate players.

Tips

 * Combining Light Strike Array with a guaranteed stun such as Vengeful Spirit's Magic Missile or Sven's Storm Hammer makes Lina a serious ganking force early on.
 * Positional items such as Blink Dagger, Force Staff or Phase Boots can help you a lot landing Light Strike Array and thus your whole spell combo without relying on other heroes.
 * Always cancel the backswing animation after casting your spells. Especially when you plan to skill Fiery Soul
 * In teamfights it can be very beneficial to quickly focus on low hp or support heroes, as Lina has very good nuking abilities.
 * Laguna Blade should not be used as a finishing blow, since that can waste most of the spell's massive damage. It is best used to cripple enemy carries or obliterate their supports; but using it when its damage far exceeds the target's remaining HP is a waste. There is a temptation to use it on fleeing heroes as it is the only one of Lina's abilities that is long range and target-unit; but it is wiser to build Blink Dagger instead to avoid having to expend it.
 * Note that owing to Pugna's ability to amplify magic damage, when combined with him Lina's burst damage becomes truly colossal to the extent that a sceptred Laguna Blade used on a decrepified enemy with full HP can often kill them outright.

Trivia

 * The original Lina Inverse "The Slayer" was modeled after the main character from the anime/manga Slayers.
 * Lina was the first hero to be made in Dota 2.
