Olorun Dongus Hard

The itemization is pretty simple here for olorun. You want to boost his attack speed as it's his main way of dealing damage (the more you attack while overflowing divinity's buff is active, the more projectiles you'll get for the second part. Olorun also has higher auto damage numbers as he has more scaling on his autos than other mages do being 25% instead of 20%). The boots choice is up to you. I get purple boots for the damage and little bit of lifesteal that's going to synergize with typhon's fang a bit when we get it online. Ring of Hecate is also picked up because Olorun works well with attack speed like I said before, it has a decent amount of lifesteal and power, but the real star of the show is its passive granting you up to 15% power and reducing their power by up to 15% (5% per auto attack hit on the enemy). This item can create a 30% power swing when you're boxing opponents as well as giving olorun a little more crit chance (because of the power increase). Typhon's fang gives you power and lifesteal. It gives you an insane amount of power and lifesteal especially with the power boots and hecate lifesteal. Telkhines ring is next because it is a decent amount of power and attack speed as well as adds free damage to your autos (the damage doesn't apply to structures) which is very helpful in burning everything down. Next is Demonic Grip for prot shred which helps you deal more damage to anything you're looking at except structures which you'll burn down anyway at this point. I love Tahuti next for the raw power and the extra shred when your target is under half hp. This last slot can be many many things. I choose mantle most of the time here because having survivability to shred longer is a thing I like to do (also 10% cdr from this item helps your ult cooldown which is a downside to the ult. You'll have 20% cdr with mantle and red pot). I've experimented with bancroft's and pythag's in this slot as well for lifesteal for typhon's for even more power but I find myself liking the survivability a bit better. If you need antiheal, you go toxic blade and you'll get it after your hecate and tyhpon's combo delaying the build from where you put it.
