1Early Stuff
Author's category · 10 items · Follow and/or Subscribe at twitch.tv/pnperplexity
Mystic Burst
Also adds hundreds of healing to each Scorn, but only when Scorn has 2 upgrades. Your second sold item if you need slots
Quicksilver Reload
Adds hundreds of healing to each Scorn. Rush this before Monster Rounds if you are healthy enough to save. Start trying to Scorn the enemies as much as possible.
Sprint Boots
Upgrade this to Enduring Speed earlier if vs certain characters with lots of slows, such as Kelvin.
2Early Optionaloptional
Author's category · 2 items
Rebuttal
Pretty much a guaranteed kill if you parry bait someone, but will only work once per person at most. Beyond that, melee resist feels very good since the burrow nerf.
Return Fire
Don't let the cost of the item bait you, this is a late game counter item to teams with many M1's. Should use while burrowed or while ulting. Having resistances makes this item better.
3Early Optional
Author's category · 9 items
Compress Cooldown
Since you are buying Superior CD next, might as well put this on the ability you will use the most in between. Will -20 seconds on ult if full CD(dimishing depending on % CD)
Duration Extender
Superior Duration
Built from Duration Extender
Great item that synergyzes with Burrow, Combo and Scourge. This is a Defensive and Offensive Spike.
4Late Game Common Optionsoptional
Author's category · 11 items · Sell Healbane and/or Quicksilver Reload for extra late game items
Spirit Resilience
Unstoppable
A good counter item to Dynamo if he keeps ulting your team. Very strong combo item with Cheat Death.
Debuff Reducer
5Vit Itemsoptional
Author's category · 10 items · Left to right, more common to less common
Metal Skin
Diviner's Kevlar
An item to buy if you are weaker and want your ults to be better. Cheaper, but worse, than getting Unstoppable and Cheat Death
Phantom Strike
A good item to buy the enemies are playing outside of Warp Stone+Dash Range constantly
6Situationaloptional
Author's category · 29 items · Left to right, more common to less common
Enduring Speed
Built from Sprint Boots
Can buy this sooner if vs many slows (Kelvin, Viscous, etc.) Or if it helps you secure Unsecured Souls before a fight
Improved Spirit
Built from Extra Spirit
Fortitude
Still good some games while ahead, allows you to stay on map and continue pressuring. Not great when behind since you are more likely to be close to base anyways
Categories appear in the author's order. Only the editor's default Early, Mid and Late sections are marked as game stages; the author's own categories keep their names. “Built from” links come from the game's item recipes.

Trophy Collector
Built from Sprint Boots
Sell if you need a slot late game, it does feel bad to lose the movespeed so I usually sell it for Enduring Speed and Juggernaut
Cold Front
Use while burrowed to set up for your unburrow, or just use it while spinning. Use on tier 1 camps with Scorn to clear them instantly
Extra Spirit
Sell if you do not need it for Tankbuster, if you need the slot, sell it and delay tankbuster upgrade
Healbane
Guardian Ward
Buffed item, pretty solid uses.
Torment Pulse
Warp Stone
This is Mo's best movement item in my opinion. You can use warp stone while burrowed to get on top of 1-story buildings and ridges. This expands Mo's getaway angles exponentially.
Tankbuster
Built from Mystic Burst
Divine Barrier
Built from Guardian Ward
Counter item to build versus Pocket and Wraith, but generally a good item even without a specific counter
Scourge
Superior Cooldown
Built from Compress Cooldown
Usually Curse this item!
Transcendent Cooldown
Built from Superior Cooldown
Arctic Blast
Built from Cold Front
Buy this as soon as some loser on the enemy team thinks Indom is your hard counter
Dispel Magic
Almost always a buy. Necessary vs Knockdowns, Decays, Seven 2, Infernus, Knife Shiv, Mirage, Haze, etc.
Cheat Death
Cheat Death+Unstoppable+Superior Duration = Someone is getting held for a long time. Build this vs fed Shiv's now that it beats Killing Blow
Witchmail
Can be decent into Infernus and Victor? Not a great item imo
Cursed Relic
Spellbreaker
Built from Debuff Reducer
Escalating Exposure
Gives damage to whole team, and a little resist.
Boundless Spirit
Echo Shard
Imbue Burrow if they are never pulling you out, imbue sandblast if many M1s
Juggernaut
Great item versus certain heros, like Haze, Infernus, Wraith, and Mirage. I sometimes delay Scourage to buy this sooner depending on the enemy team.
Indomitable
Veil Walker
VERY GOOD ITEM IF YOU GET USED TO USING IT
Colossus
Reactive Barrier
Can be a life saver vs quick stuns such as Abrams Charge, not incredibly needed vs Bebop since you can use burrow after being hooked anyways
Plated Armor
Bullet Resilience
Buy when needed, can buy at any point in the game. Generally bullet resist is less needed than spirit resist because of burrow. But if you are getting pulled out of burrow consistently may be needed.
Knockdown
Very good item versus most heros, but Grey Talon, Lash, and Vindicta especially
Decay
Newly buffed and does a very large amount of damage, though slowly. It is also the best anti-heal other than Spirit Burn
Vortex Web
Spiritual Overflow
Cultist Sacrifice
Heroic Aura
Silence Wave
Tempo Spirit Sap into mid game Silence Wave may be strong now
Suppressor
Radiant Regeneration
Infuser
Stamina Mastery
Spirit Shielding
Weighted Shots
Stalker
Opening Rounds
Headhunter
Alchemical Fire
Ballistic Enchantment
Berserker
Tesla Bullets
Mercurial Magnum
