Edit patch 4.19
I've just simplify this quick guide here for new patch. They did some minor changes on Hachiman, buffing the 1 (arrows scaling) but decreasing the damage I think just a lil' bit and other minor changes (ult dmg scale). This is neither a nerf or a buff, just some tuning balances and it's alright. But, they did buffed The Crusher quite a bit (increase attack speed from 15% to 20%). I had already include The Crusher in my Hachiman builds and I knew it would be a good item on him but it wasn't quite efficient enough (Qinn's or even Titan's or Jotunn's maybe were as good or better) but now I can confirm without any doubt that The Crusher is for sure the way to go and will be a standard build on Hachiman.
Intro and playstyle
Hi guys. So here's some builds examples for Hachiman, the new God. I haven't played a lot of hunters lately because I was bored with their playstyle, had played a lot of hunters while I start playing the game a few years ago but Hachiman has an interesting kit. It is simple, easy to play, straight forward but it has a more ganking assassin-like playstyle. With his 3, you can stun an enemy God, than throw your 2 right there and beneficit from the attack speed increase. And if he escapes, you can finish him with your 1 or ult. So he can be more agressive than some other hunters, in a way, even though you won't hit the stun all the time. It is challenging and it's fine this way. His ult is also a CC immunity and a slow, so that's really conveniant. You can either attack with it, escape with it or secure kills. Don't hesitate to use your ult for team attacks, to slow ennemies so your team can secure kills. Not a hard CC ability but the slow is high (scaling from 25 to 45%) and lasts 1.5s. Powerful ult there.
Builds
For what I've been experimenting, Wind Demon and The Crusher are really the key here. Obviously a little bit of cooldown is fun on Hachiman because his cooldown on his 2 is kinda high. Also the pen is a must with crit. For boxing potential, Devourer's Gauntlets and The Executioner are a the way to go obviously.
Abilities
So you should max his 2 first as it is his clear and most powerful ability and his 1 second. Put only one point in his 3 and then max it last. Put points in ult when possible.
Outro
There's a bunch of other items that could be interesting to try on Hachiman but from few games I played in Arena, the build I provided here works best. Anyways, have fun guys and remember, comments are appreciated. Thanks for reading.
Yeah, I think that's a good start, using Bluestone Pendant should work well with Heavenly Banner. That said, your skill order should probably be redone. You put the first 2 into Banner, and in Conquest, that won't work. Stylize it so it works for all modes, by leveling Banner, then Iai, then Banner again.
I also feel that he's probably better as a crit attacker. I'm down with your build 1...it's similar to my standard Medusa one, with the exception of getting DB 5th instead of 6th, and Rage instead of Wind Demon.
For build 2, I do note your purpose for The Crusher providing some CDR effect, but think you're stunting your overall DPS by only getting the 1 crit item. Hunters can burst pretty quickly, so you may or may not even need anti-heal. If you do want higher attack speed, though, I'd probably suggest, since you get Devo's 1st in that build, get Ninja Tabi 2nd, and then get DB last rather than Crusher.
In all cases, actually, I suggest switching to Ninja Tabi late-game.
As for build 3, it's okay mixing Qin's and crit, but it's not quite optimal. In a case where you're skipping lifesteal (say a teamafight mode like Arena), you might consider 3x crit, with either Rage (buy it earlier to get stacks) or Poisoned Star added to the mix...their cost is reasonable so will allow you to get it online more quickly.
Unless you KNOW for a fact it's a killer item for him...just completely eradicate Atalanta's Bow from your other items list. You already get boosted move speed from Wind Demon's passive, and the item just sort of sucks.
If you include Ichaival in the other items list, you should include its counterpart, Silverbranch Bow.
In your writeup, you mention he doesn't have a slow (in the Intro/playstyle) right after you talked about his ult...which has a slow.
As for Rangda's Mask, I think that might be a slightly risky item, and should be at most an option, with Bumba's Mask being another.
Anyway, those are my opinions...let me know what you think.
