LETHALITY :  ⇒ 18
Grants even more movement speed. Lethality up, attack damage down.
Doubling down on Ghostblade’s identity as the mobility-oriented Dirk upgrade, now that it’s the only one that grants movement speed. It already offers every damage stat a physical assassin wants (attack damage, lethality, and cooldown reduction) so we didn’t need to do much else here.
TOTAL COST : 2900 gold (unchanged)
OUT OF COMBAT MOVEMENT SPEED :  ⇒ 40
LETHALITY :  ⇒ 18
ATTACK DAMAGE :  ⇒ 55
Up until the introduction of Lethality, Ghostblade granted 20 flat armor penetration. We wanted to avoid shrinking that number during the transition away from flat penetration, which was a big enough change to get used to on its own. Now that Lethality’s found its place in the stats system, we’re bringing Ghostblade in line with Dirk’s other upgrades.
LETHALITY :  ⇒ 15
Move faster. Active no longer grants attack speed.
The base stats attached to Youmuu’s Ghostblade were a bit of a grab-bag for physical damage, making it useful for basically every AD-focused champion. Most of its unintended users benefit too much from the active’s attack speed, so we’re removing it.
TOTAL COST : [3200 gold] ⇒ 2900 gold
COMBINE COST : [1000 gold] ⇒ 700 gold
FLAT ARMOR PENETRATION No longer grants +20 flat armor penetration
LETHALITY UNIQUE Passive: + 20 lethality
KNIVES MAKE YOU FASTER UNIQUE Passive: +20 movement speed while out of combat
IT’S A GHOST BLADE UNIQUE Active: Grants [+40% attack speed and +20% movement speed for 6 seconds (45 second cooldown)] ⇒ Grants +20% movement speed and ignore unit collision for 6 seconds (45 second cooldown)
Just as marksmen scale with critical strike and attack speed, casters and assassins scale with cooldown reduction and flat armor penetration. Youmuu's Ghostblade fills this ‘core scaling item’ niche for casters and assassins, but also everyone who builds AD due to how much power it brings in raw stats. We want Ghostblade to stay useful for the classes it serves, so rather than reduce its secondary stats, we're shaving off a bit of attack damage. Combined with buffs to other AD items this patch, we're hoping the relative difference is sufficient to create a meaningful tradeoff for picking Youmuu's if CDR and flat pen aren’t your main stats.
ATTACK DAMAGE :  ⇒ 60
No longer has crit, but has wayyy more damage.
Simply put, Ghostblade often lived in the valley between 'An assassin item that has crit I don't need' and 'A marksman item that isn't as good as Phantom Dancer'. With Marksman getting a host of new toys, we're refocusing Ghostblade as a much-needed buy for Assassins.
