thank you for apologizing.
this is the path that i would expect to be used in order to make it exactly as it is.
+
+ ~1500 gold
those build paths i placed above are suggestions that i think would fill the voids in our current item shop by providing alternatives to popular items or not so popular items.




the first one would be something along the lines of a melee physical casters alternative to essence reaver.
the second one would be an alternative to rageblade with casting in mind and not just basic attacking
the third one is an alternative to phantom dancer that is basically a basic attack version of ludens echo which would provide movement speed, attack speed, ability power, and criticals. i think this would give infinity edge a run for its money.
the third one is an alternative to nashoors tooth that's built more for a juggernaut.
the lightning passive on all of those builds is removed and replaced with more specific passives that would cater to the item itself. the image appears to be a lightning hand bow so it would make sense to redesign it as a critical item with magic properties though we have 2 items already that build from the shard.
so even something like
or
+
or
+
or 
since the fact of the matter is that the item grants 50% attack speed it'd be granting more attack speed than every item in the game except nashoors tooth. the hp granted is so low that you'd either have to combine it with a single ruby gem and pay the difference in gold or increase the stats on the original weapon. and then of course the lightning passive is already taken over by statikk shiv.
personally to me it just makes more sense to give it new stats.
