The reason why Ohmwreaker is in a bad state

Wait, this game has towers?

no, it's because building an item for tower dives when you can just juggle the aggro it's dumb.

it's too situational as well.

Or either make it a mid tier item or make turrets relevant

I think it should be made into a sight stone variant with higher cd, lower duration and no / few stats. That way it has its niche as the tower blocker, but early enough to be actually relevant as an item. Make it a tank utility sights tone upgrade
