An extremely basic and simple mo build based on my preferences and observations while rising through the ranks. Find me at @mistermantis on Discord!
1Early game
Game stage · 7 items · L->R, delay for an 800/1.6k if needed.
Mystic Expansion
beeg Scorb :D (extends Scorn to 10.8m, MASSIVE.)
Mystic Burst
Does 2 things in the build before Tankbuster -- applies poke pressure with T1 Sand Blast and increases T1 Scorn's healing by a good amount in the early game.
Cold Front
Use for extra burst damage in lane and as a tool to clear waves/camps. Treat this item as a flex slot and sell it when you want something better (like a T4.)
2Important 800 ~ 1.6k Vitalityoptional
Author's category · 4 items
Rebuttal
People melee a whole lot in higher ranks and even if they don't they'll never expect the parry off cooldown. Sell after lane unless you're getting all of the value ever.
Enduring Speed
Weapon Shielding
M1 carries are very common and this item makes taking trades with them much better. Be wary of the CD though.
3Mid game
Game stage · 7 items · Vaguely L->R, delay and swap order as needed. (VEIL BEFORE TANK ALWAYS)
Mystic Regeneration
>
Radiant Regeneration
Built from Mystic Regeneration
Pretty good when you slam yourself into a large teamfight and profit by becoming sustain itself. I also use this item for the speed, casting burrow with this off cooldown makes you insanely fast.
Veil Walker
4Important 3.2k Vitalityoptional
Author's category · 4 items
Counterspell
*Ultrakill parry noise* (Same thing as Dispel but for things that interact with you physically. If it hurts you, you can more than like counterspell it.)
Spirit Resilience
Anti-spirbit :D (can optionally sell this late for Witchmail if you got it, as both is just unecessary due to the deminishing returns of resistances.)
5Late game
Game stage · 7 items · Situational, I prefer Sup -> Trans -> Witchmail usually.
Superior Cooldown
Here to upgrade into Transcendant.
Transcendent Cooldown
Built from Superior Cooldown
Affects Radiant, Veil walker, Tankbuster, Torment Pulse, and any other barrier/active you have. One of my favorites.
Witchmail
6Situational Early ~ Mid Game Countersoptional
Author's category · 4 items
Debuff Reducer
Into a lane that has a lot of scary debuffs like Shiv's knives or Infernus's Afterburn. Can subsequently upgrade this into Unstoppable or Spellbreaker, or sell if it's no longer a necessity.
Reactive Barrier
Not much to say on Reactive. Buy into heavy CC or if theres one dude that's plowing you from behind without consent and you want a breather.
7Late Options ~ Counterbuysoptional
Author's category · 7 items
Escalating Exposure
It's a good item, but Mo makes much better use of having many green items and being a large, unkillable tank. I enjoy this in very late games, but little else is very noteworthy.
Magic Carpet
Playstyle choice, funny but situationally good. Great for gap closing. Good escape/chase tool.
Arctic Blast
8Options (Early ~ Late)optional
Author's category · 4 items · If'n you want.
Improved Spirit
Built from Extra Spirit
This upgrade is here if you wanted Warp Stone over Veil Walker, here so we can still reliably hit 165+ dmg on Scorn for Tankbuster.
Alchemical Fire
Alcfire is good if your team has one or two fed gun carries or has mostly weapon damage, throw into teamfights or before you combo.

|---|
Trophy Collector
Despite it being a T2, I don't usually sell this late unless I really desperately need to. The true last sell. (Roaming usually begins once you have this, so make the most of it with combo off CD.)
Fortitude
For roaming throughout the early to late game, sell as a slot for a T4 post like 30mins. Generally should be your 2nd to last sell. (Also, Green 4.8k.)
Extra Spirit
Cheap spirit. Sell once we don't need it to hit 165 dmg on Scorn.
Healbane
A mainstay usually, keep until you have either stronger antiheal or get a T4 late. (Can also be swapped for another 1.6k or 3.2k green. Keep if into spirit vic or geist.)
Spirit Shielding
Same description as Weapon Shielding but fitted for Spirit. Both are common, just pick your poison.
Hit a veil after you've casted burrow to zip around the Cursed Apple at mach fuck, trust me man it's amazing. Veil Walker also gives us +10 Spirit, enough to reliably proc Tankbuster.
Tankbuster
Built from Mystic Burst
Makes Scorn's mid game damage actually scary on top of also piling buckets of healing into Scorn.
Torment Pulse
Close range demon. Helps out combos damage and provides ample dps when running some poor idiot down on sidelane. Replaces Extra Spirit post Tankbuster generally but kind of a suggestion in this build.
Greater Expansion
Built from Mystic Expansion
Affects all of Mo's kit, but one of the bigger things is it affects items too. Extends Torment pulse to about 12m minus however many Trophy stacks you have, and works with other items as well.
Dispel Magic
For debuffs, abilities and items with nasty after-effects. Swap often with other 3.2k green counters, but commonly my most used 3.2k green counter other than just the flat resistance items.
Bullet Resilience
Anti-boolet :D
Warp Stone
Get out of spooky slows or scary ults. (Haze, Victor... etc.) General alternative to Veil.
Scourge
Huge spirit res, DBR and DOT? Yummy. Good into M1 carries, and even better into heavy spirit comps. #Scourgebestitem (feels good if you're ahead as well.)
Colossus
Fat 25% health buff, genuinely goated. Ough my belly... it's all inflated and fat right now...
Spirit Burn
Hit phantom and scorn and make an explosion happen. Big antiheal, and great with escalating. I tend to sell Healbane for this, but keep it if into spirit Victor or Geist. (or other big heals.)
Frenzy
Genuinely underrated -- the ROF buff feels great and 40% DBR is NOTHING to scoff at. Also doubles as a capable escape tool with the 4m/s movespeed buff and aforementioned debuff resist.
Return Fire
Mid-Late game counterbuy for heavy gun comps, but finds value in spirit as well. Theres a certain psychological factor to Rfire that makes people not wanna shoot you. Abuse it.
Metal Skin
Good into heavy bullet but in my opinion? WORSE than Bullet Res. This is generally recommended for Haze/Infern but their debuffs still apply through it, good into Venator however.
Built from Cold Front
Indom shredder. And if you kept it this long, should also proc Tankbuster. Play around that if so.
Phantom Strike
One of my personal favorite items for Mo, catching up with super fast and agile characters is hard and this expedites that process. Phantom strike into a combo is a "combo" that I'll nvr get tired of.
Unstoppable
Built from Debuff Reducer
Spellbreaker
Built from Debuff Reducer
With Trans it's a low enough cooldown to let you facetank heavy spirit and come out relatively unharmed in most cases. The DBR is also great, combined with Scourge you facetank like no other.
Plated Armor
Great anti-bullet item. If you get unlucky it's unfortunate but into an ulting haze (or infernus, or... uh, any other gun hypercarry) it feels great especially since Mo is a walking hitbox.
Knockdown
Use as the bar for Combo reaches the B or O and warpstone into the air for chain CC.
