true, true.

But with the build posted above i've one-combo'd most non-tanks i've faced. Going above that area on AP seems to be fairly pointless. Why be able to do (example) 4500 damage if 4000 will kill them?
Gold would be better spent on other stats that need pushing up.

Though i must admit the passive on deathfire (when i remember to use it) is great for the first second or 2 after the tank initiates. But looking back on your previous post... i shouldn't be that close in the first place.

again, thanks for the feedback, still trying to root out anything sub-par and improve.

Still the same thing applys. Once you get Archangel's Staff you should have very few mana problems, I personally pick up clarity for early kills. So the 500 mana goes to waste. If you want cooldown reduction perhaps you should go with Deathfire Grasp. Because sure you can use your abilities more often but you won't be doing enough damage to make it worthwhile.

thanks for the feedback,
just to explain the frozen heart thing, aswell as the armor and slow attackspeed, don't overlook the 500 mana and 25% CDR, i've had my ulti down to 24 seconds on max rank with frozen heart.

But i see what you mean with the scepter. Guess my playstyle(<< net sarcasm) of "right on the edge of the fight" dosen't suite everyone. i'm mainly in rage to make sure i get my snare off xD

Good guide although I don't know about Abyssal Scepter as the passive is thrown away because as Lux you should never be that close to a enemy champion. Also I personally dont think that you should pick up defensive items such as Frozen Heart because it just never comes to good use. Sure it slows their attack speed but if you are getting focused chances are you are going to die. Also because you didn't get Prismatic Barrier I am assuming this is a more carry orientated build therefore you should be getting all AP and not Frozen Heart. Of course it does add some survivability you are still extremely squishy and I find it to be a waste of time. Good Guide nonetheless :)
