User blog comment:OwenNewo/Do you understand the bond? My experience with the Armordillo/@comment-4431813-20120916130057/@comment-4431813-20120916154650

Imo, Nida doesn't even need boots at the beginning that much. Chalice gives equal amount of bare mp/5, the difference is in passive. But Fiendish codex gives you some ap (that makes 30 *  0.65 * ~2 -> more than 40 bonus dmg on spear from start), same bare mp/5 and 10% cdr. And I suggest running Athenes before rabadon, unless you can get needlesly AND chalice after 1st trip back. I often run bootless until I get rabadon and Athenes.
