Another patch! Who would've known!
This patch, we're taking a gander at some old friends who have been struggling for a while—Udyr! Nidalee! Sivir! How we've missed you!—and readjusting a couple of offenders that have been toeing the line (hint: trees, daggers, and gems).

Q - RAZOR SHURIKEN COMBO BUGFIX Zed's Shadow will no longer recast Q - Razor Shuriken when performing his Zed's W-Q-W combo

E - SHADOW SLASH VFX BUGFIX Zed's Shadow will now properly play one instance of E - Shadow Slash's VFX, not two, when casting his W-W-E combo at less than W - Living Shadow's range
