Talk:Rabadon's Deathcap/@comment-1663379-20120510162644/@comment-4990650-20120524013104

It rly depend on how well are you doing and which champ are you using. If you need zero survavibility(which nerver happens) then lets talk.

If your abilities are all ( or almost) single target, a DFG is cheaper and still help your job done .If all your abilities have 10 or more seconds CD, some CDR will boots your DPS more than a Deathcap. Champ like Anivia cant rush Deathcap cause she need mana. Other than that the Deathcap is extremely cost effective even when you only have AP from itself+runes+mastery+Doran. If your kit scale well with AP ( which alway do for a mage) get it as soon as you can.
