The way i would build ahri is to get RoA as a first item. In her strategy it says she's a bit more durable for an assasin, and i noticed that her mana runs out very fast if you harass. So i rush catalyst and become a durable mage. In some cases i would build every S3 item with AP and health so that the enemy team has a lot of trouble taking me out.

Rod of ages, Rylai's, Liandry's, Ohmwrecker, Sorc shoes, and Deathcap. Though you can replace an ohmwrecker with something else to increase her damage.
