An item build for Lina that gears toward fast hero killing for early-mid game and massive auto-attack power late game.

Shadow Blade Combos:
1. LSA / DS / Laguna
2. LSA / DS
3. DS / Laguna

[Early]
-Dragon Slave to Last Hit AND harass
-Apply pressure from full attack range
-LSA only if they come at you
-Farm till Shadow Blade

[Mid]
-Roam/Gank with Shadow Blade (Combo 1 or 3)
-Farm until Laguna Blade ready
-Carry TP Scrolls
-Keep replenishing mana at fountain

[Late]
-Use only two spells in Shadow Blade (Combo 2 or 3)
-Keep mana over 1000 during team push
-Reserve Laguna for enemy Carries

Notes:
Laguna Blade Lv.3 will always eat up more than half your mana pool without intelligence items so save it for carries or guaranteed kills. Otherwise you won't have reserve mana for Fiery Soul DPS.

SB combo 1 is the bread and butter for early game kills.

SB combo 2 is when you're low on mana and is more reliable once Lina has DPS items

SB combo 3 has the best damage output considering that it gives Lina more time to fire off auto-attacks before the enemy can respond with a bkb/disable.
