Item Idea for the assassin rework
This is an idea I had for an item for the upcoming assassin rework that IMO could make balancing AD assassins much easier.
"Insert name here" +65 AD +250 Mana +10% Coodown Reduction Unique Passive: Spellblade: Using an ability empowers the next basic attack within 3 seconds, that deals 75% Base AD (+50% Bonus AD) bonus physical damage. It has mana because it would build out of sheen. Well, this item would be great for champions such as Talon or Zed, and RIOT would be able to balance them around this. Also it would be useful for Corki, who is weak ATM, and other Spellblade users such as Gangplank or Ezreal, who could see tweaks around the existence of this item.
If you think it is unbalanced tell me in what way and I would try my best to change it. Also, I accept suggestions for a name for the item.
