To this day, remains the item they add to recipes when they can't think of anything else. They just inflate the **** out of the AP it gives, and sometimes the CDR. It makes sense on Athene's Unholy Grail because the entire point of that item is spamming spells.
Not worth rushing it anymore. If you're going to buy Athenes as AP mid, defently get the Chalice first (unless you're fighting against AD Mid eg. Talon along the whole early game, as you wont need the MR anymore)
This is the biggest "icing on the cake" item. It's nice, but it doesn't give you anything mandatory. The fact that this was added to Blackfire Torch just jacked the price up by 1000 gold, and now it's no longer worth buying on most champs.
I often go for this early on support Taric, as 7regen and 10cdr is amazing early on. I usually buy this after my PS, HoG and boots if I got a lot of assists and a good laning phase, and then upgrade it into a Nashor's Tooth (if laning phase didnt go so well I tend to find other ways to get cdr like Frozen Heart and Randuins).
You have to ask, why does this book(yes codex is a type of book) have a picture of a an Antelope Skull on the cover. I guess there is something majestic about that but in the end you might as well call it the Colt Codex, or Manuscript of ADCD, and I also wonder if this was a Hardback, would it cost more; I guess for collectors prestige.
