As you can see, there are many paths for you to choose. As always, depends of your playstyle and what's what you have to face.

-1st, Mage's blessing + t1 helmet (vs phys): Gotta say this is my favourite out of all. Gives you good early dmg for push and defense.

-2nd, Mage's blessing + t1 warlock: This is the most agressive start, just dmg . (i'd only do it if im against smth that has literally no pressure, like aphro)

-3rd, Mage's blessing + t1 voidstone (vs mag): Basically its the same start of the helmet but vs magicals. (i may not do it if i have to get pestilence, instead I'd do the 2nd one)

-4th, Warrior's Blessing + t1 warlock: This is the most defensive start. (i'd normally not do this unless they have a ton of pressure, and with pressure I mean kill potential, like King Arthur or Camazotz)

-5th, t2 Warlocks: This start its like the 2nd one, but instead rushing warlocks. Difference is, your early clear is going to be worse and youre losing the cd.

PS: You should start with blink, since you need thorns aswell later on. Blink has more value than thorns early. You can always force their dashes with your jump/blink and then go in again.

AND NOPE; BANCROFT IS NOT A VIABLE OPTION. You win lane hard ? Prob, but You're going to be an easy target the entire early stages of the game. Even if you manage to survive, its not worth to win lane if you're going to lose the game, something that will happen if you dont end the game before 15 mins. ( not likely) You are missing defense or health if you go for bancrofts. The only value of that item it's lifesteal and you cant rely on that since antiheal items are pretty strong.

This is going to be your build in most cases I'd say. Pestilence is mostly needed in every single game (if not you can replace it for voidstone), Jade Emperor's I'd say its the best item for Hades to deal with warriors in the early stages of the game (do boots+ jade), but you do need to replace it at some point for nemean (basically hunters are going to kill you in your ult in late game, nemean helps a lot against that + thorns aswell)

Its up to you to do the right order, normally i'd always get nemean before getting spirit robe, but as always, it depends of how the game goes. At the very end, you can replace boots for soul reaver, its the most valuable dmg item in late.
