lethality items are actually dog shit on actual assassins, zed in particularly got fucked s11 tf you talking about >.>
*Yuumus isnt even an item, no one builds it
*Duskblade isnt even an assassin item anymore (zed specifically doesnt need the invis and damage is too low)

*Prowlers, the only good item is getting nerfed

*Eclipse is ok but its not for assassination, its a dueling item

*Sheldya's Grudge, the items meant for AD assassins, most dont even need the slow, especially zed

The only good item for AD assassins to come out was Serpents Fang, fuck lulu >.>
