Actually, it stacks up to 80. 2 AP per minute over the time period of 10 minutes. 60 initial AP.

I am aware that Rod of Ages gives power, but raw power is not my intention. Having that extra AS gives a higher DPS, which is an important thing to consider. That is why I get a mixture of things.

With the runes I have and with a Doran's Ring starter, I have a total of 45 AP. The Fiendish Codex adds 30 to that, making it 75 (without the AP percentage increase from masteries). This overall gives a higher DPS to allow him to have an actual presence in lane. After boots of speed, Catalyst, and finally Ionian Boots, I usually have enough for a Blasting Wand depending on my progress in lane. This increases my AP to 115. Finishing RoA would only give me 20 AP initially and increase 40 over time.

What I'm trying to say is there is no downfall in building a little DPS instead of raw damage, especially by delaying it for just one item such as the Codex that gives him a rather intimidating presence in lane.
