I'm starting to play DoTA, and in order to not get lost in the game, I keep a hero guide open. The other day, I picked the Nerubian Assasin, and when I checked his entry in the guide and started to follow the item order, I couldn't find the third item on the Core Items list.
The item functions by storing up charges every time an opponent casts a spell near by, and then you can use these charges to gain health and mana. Additionally, it is the result of mixing other items together in a recipe.
I was unable to find that item in particular in a more general item guide.
Can anyone identify this item for me?
