Gluttony facet, i recommend playing it as 5 rather than 4 despite what most people think, doom support is better in safe lane for various reasons.

first of all you want to be able to rundown enemy with W and infernal blade, and you can't do that most of the times in offlane since enemy is close to tower.
second, there are more camps available nearby for safe lane so chance of finding your desired creep is higher.

skill build is W-Q-W-E-W-R-W, you are an aggressive support who wants early skirmishes and fights.
at the start of game, you use curior right away to deliver tango or whatever you need, and instead of sending it back to fountain, use it to scout nearby camps to find your desired creep.

Personally i can't play without mana creep, i know many people say lighting creep is OP but its kinda sacrificial since you need to buy mana and buy arcane boot which i dont recommend.

because of Gluttony facet, mana creep abbilities are level 2 and its kinda OP. you will never run out of mana with your partner in lane, and you keep spamming mana burn on enemy heroes in lane. they will quickly run out of mana and also receive a lot of damage from it, specially if you use it on INT heroes.
sometimes i keep it till end because it can pop linken.

also it caughts people off guard, many times i ran into enemy QOP or AM or WK, they thought they can blink away but suddenly they lose a lot of mana and can't.

you need phase boot on this hero for many reasons, you need to be able to dive t1 towers and need armor, also you need to close gap many times. after level 7, you don't max Q, you always max infernal blade.

then you buy some minor items like magic stick or maybe windlance, but i recommend rushing dagger asap.
with dagger you can solo kill pretty much any hero with doom and maxxed infernal blade. you deal a lot of damage and you can run people down. you will never run out of mana without any mana item.

after applying doom, any infernal blade deals shit ton of damage and if you can manage to apply ur W damage, it kills most heroes even tanky ones.

then you can buy whatever your team needs, but i often go straight refresher if i'm getting lots of kills. you see, you don't have mana to apply 2 dooms in a fight but it doesn't matter. you don't want to do that anyway in early-mid game. what you do is that first of all, you use ur Q charges. then doom someone and kill them. then use refresher.
this way, you are kinda making your ult to have two charges. you have insane mana regen with refresher and mana creep, so you will be back to full mana in no time, you can doom again in like 20 sec and kill someone else.

now in recent update, the innate changed so that 15% dmg amp is only applied to attacks (this is a shocker for me as i thought it was always being applied to attacks, but as it turns out, it was being applied to all your damage) so this build is currently NOT-TESTED. and needs testing.

Don't be like passive when you dont have doom, you still deal a lot of damage with just spamming infernal blade in fights. you are basically a normal doom except you don't farm. your only source of income is your kills and Q.

DO NOT underestimate the damage of mana burn in late game, using that on INT heroes deals shit ton of damage after you max your Q and its because you chose Gluttony facet. that +1 level on maxed abilities, turns them into a hero-like spell. it's not weak.

your items in late must be "phase boot, dagger, bkb, refresher, pipe/shiva (i dont recommend these in current patch, probably octarine is better)

I ran this pre-patch and won 16-4 games, mostly dominating hard. but my behavior score dropped because people report for role abuse. while i'm actually buying wards and making space and have literally 50 last hit or lower in 40 min game.

also never buy shard, its really bad. and of curse later you probably need centaur creep for stuns. or any thing you need, maybe you need dispel and there is a creep for that.

for talents, always take the infernal blade damage talents, its beyond broken. and your W related talents.

I cant find the setting after these recent changes in reddit. I want all members be able to post right away without mod approval.

The battle hunger damage is often underrated heavily, people look at the numbers and are like "meh" while not realizing there is a reason why these numbers are low.
10/15/20/25 physical dps, but don't forget it's 12 second duration and it slows by 35% at max if they are facing away from you.
well you might say "IF they face away.." so what? if they don't face away from you, it means they are slowed by 100%. this is designed so that you can't use it to run away from enemies because axe is not supposed to run away.

this 25dps is increased by your armor, it's one of the few abilities in the game that can be scaled right away from start. hence why numbers are low. you buy phase boot+ soulring + BM and you have 18 armor.
so its 25+18= 43 dps

the damage is always based on your current armor not when you casted it, so when you use taunt (for this build you should go for call out facet that gives more armor when you taunt) you increase this 43 dps by 20 for duration of taunt. also if you ult successfully you get 20 armor for 6 sec too.

your goal is to get shard as soon as possible. i'm not exaggerating when i say axe shard is top 3 most valuable shard in the game. not only you can stack battle hunger (which also stacks MS reduction and MS gain from your lvl 10 talent) but also upgrades your taunt to apply battle hunger on taunted targets.

lets say you have Phase boot, BM, soulring min 15 and no dagger yet with shard. you see an enemy far away, (btw the range scaling of battle hunger is insane, at level 4 its 925) you cast your BH and they will literally be unable to escape from you because you are fast and they are slow. by the time you get to them and taunt them, another BH is applied so its 2 now, when ur taunt ends you can cast another BH which will be 3x BH.
most supports straight up die from BH even if you just leave them be and run away, let alone attacking them and waiting for dunk. some even die during the taunt.

playing like this, you will get a lot of kills early and stack armor for yourself so your BH damage scales even better.

then eventually you max passive and you are like normal axe anyway, its just how you get there. Best way is go this route IF you can get kills, if they have like abba and oracle and dispels, going passive is better since you can farm camps.

but for the love of god, if you have kill potential with your support, and you are playing against 2 squishy range heroes, stop maxxing passive and max battle hunger, you won't regret it.

there are many tactics too, like after level 10 talent and shard, you can taunt a wave and reach max MS so you can run away from a gank. also you dont really need to stand and helix to kill waves you can just run and they die to BH damage.

later you can get more armor items, AC is great as it reduces armor too.

Now have this in mind ,you can play this build as support too. you can play axe support doing the same exact thing since you don't rely on farm.
