Screw IBG, Nasus doesn't need more slows. He just needs to be faster.
Zephyr a possibility at all? I like going IBG and Tabi when I'm facing a heaver AD team so I need Zephyr due to not getting Merc's. Trinity certainly would be more damage.
Maybe to replace my boots, but Nasus doesn't really benefit from ASPD, CDR is wasted with FH+SV, AP is only a slight bonus on R+E. Almost every stat is wasted. --- If inflaton turns $3 into $0, then $6 turns into $3. -Orca
