Can you make Vayne’s W an active ability?
How it would work:
It has a 6/5/4/3/2 second cooldown. It costs 30 mana all ranks.
When activated, Vayne’s next three attacks apply silver bolts. If Vayne manages to hit three silver bolts on an enemy target, they take bonus true damage.
This forces Vayne to stick onto one target at a time. It can be used as an anti-tank tool but tanks do not die in 2 seconds to Vayne alone. She doesn’t destroy squishy targets early game because long cd.
