Balanced Manica

I think the whole point of this is the item's effect is too good for its cost. I mean when going by your example, OD would be COMPLETELY broken. A not-so-specially farmed OD would reach level 16 and just 1-shot the enemy team - all while absolutely DOMINATING the laning phase and hitting MORE like a train late game. All for 2000 gold. I'm sorry but this really isn't the type of item for dota.

Maybe making its components more expensive and at the same time increasing recipe cost is a nice way to balance(a bit). Maybe its components should be similar to Aghanim's Scepter. That way, you'd be only be able to get it late game (unless you rush it).

Idea: Make it only improve 1 specific skill of few specific heroes. Basically, it'd work the same way as Aghanim's Scepter, 'cept that it only improves one of your non-ultimate abilities. Thoughts?

P.S. Don't make an upgrade for Phantom Lancer XD.

It definitely needs to be scaled down but I would like to keep it as a item which you pick up on heroes who don't farm much mostly supports or mid game heroes who lose power with there spell in the late game, i'll think of a way to balance it

One question: Does this work on chance-based abilities? A 100% chance Coup de Grace is not something you wanna see, don't you?

It only works on magic, pure and composite based spells and that I am pretty sure is physical so it would have no effect.

I changed the item and reworked the numbers on the example spells to show the new effects.
