Zed Q damage down by 50% for base and scaling
Zed shadow now passively increases Q damage by 20/40/60/80/100%
This means LVL 1 shadow his Q will do 60% damage of current value, only after shadow is LVL 5 does it go back to live values
This heavily reduces his damage early game, letting. Him keep his safety in exchange for a much more delayed power spoke
Alternative idea
Zed Q loses 50% damage, landing Q marks the target with menacing shadows
Menacing shadows - causes zeds next shuriken that hits you to deal 100% bonus damage , this debuff lasts 10 seconds
This means if zed lands one shuriken he won't do much damage, if he lands Q and shadow Q he will still deal decent damage, if he lands Q then a Q+shadow Q he will deal live damage values
This means getting hit by one won't be overly devastating as it is now, but if he keeps hitting you with them then it will hurt like love values do
This is further effective by making zed want to land a Q on his "kill target" before he ults and goes in to return his kill potential to love for the ult combo
This puts more feast famine onto zed for having to land his skill shots (even with his ult) to deal meaningful damage because now he has to land a Q before going in with ult for it to deal decent damage
While at the same time this will be a minor nerf to zeds that can reliably land thier shuriken
"This will separate the good zeds from the great zeds"
