It adds 100~(100*Crit damage modifier) magic damage to your autoattack as an on-hit effect, which means that your AD damage will pop in red numbers, and this item's damage will pop in blue numers. Together in the same autoattack, but not together in the same damage.

All in all, this goes into the old PD path, and Runaan's goes into it's own path with other items. Of course, I'm not trying to say that you can't build them together. It depends on the character you're building them on, tho.
