Total cost of that setup was around 20 div. Check pob notes for an explanation of Phrecia + Victario's combo ("totally intended interaction").
Overall feels suprisingly nice, even with such a bare bones, low investment setup. Totem playstyle is pretty safe most of the time, single target is suprisingly good even on 70% more life t15 Drox. Biggest problem of the build is mana cost, without any mitigation one totem placement costs 135 mana, the loss of the mana cost flask suffix really, really hurts. Next to that I'd say focussing on cast speed and totem placement speed are the biggest factors.
I'm pretty sure the Phrecia Generosity interaction will be removed next league, but there are other options for better defenses.
As always, if you were to put in Progenesis, Mageblood, a lot more divs, etc, then the build would perform much better.
Also this is not a final version of this build, I'll continue playing around with it for some time.
