Thanks for the tip about MR. I knew in the back of my head that it reduces by a percentage, but I hadn't math'd it out. The damage is the same whether you calculate it by 1 hit or two seperate hits (I feel like it shouldn't, but that's how the numbers work). For kicks, if two Vel'Koz's running a total of 30 ap runes with 4 ranks in W at lv7 hit each other with the afore-mentioned spell, one with sorc boots+dorans+HG, the other with sorc boots+dorans+chalice+amp tome, the chalice-build will do 16 more damage (assuming no defensive masteries or runes), but will lose a greater proportion of their health from the attack.

When I was talking about items, I wasn't trying to make an unquestionably strict and concrete build path. I was just reiterating that i disaprove of the mana-heavy "Ziggs" build that everyone seems focused on. I completely agree that Banshee's is a great defensive choice. Any build should have some flex to it.

And RE: the windwall. I only played one game against him and everyone agrees that the windwall does block most of Vel's attacks. Perhaps it was a bug or just narrowly missed timing.
