Veil Walker

Veil Walker

Vitality T33,200 souls

Can go invis for sneaky combo's, also has very good healing uptime with Transcendent Cooldown. You can rush this before the other 3.2k soul items if you are roaming around

Rebuttal

Rebuttal

Vitality T1800 souls

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.

Rusted BarrelActive

Rusted Barrel

Spirit T1800 souls

Vs double M1 lanes this is pretty good. They keep buffing it. IT HAS TO BE GOOD EVENTUALLY

Core Stuff

Sell Extra Spirit if slotlocked

Warp StoneActive

Warp Stone

Vitality T33,200 souls

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.

Compress Cooldown

Compress Cooldown

Spirit T21,600 soulsImbue
Return FireActive

Return Fire

Vitality T21,600 souls

The cost of this item is a bait, this is a mid-late game counter item for a team of 3+ M1 carries.

Superior Cooldown

Superior Cooldown

Spirit T33,200 souls

Great item, lowers all ability cooldowns.

Duration Extender

Duration Extender

Spirit T21,600 soulsImbue

If your ult is on a long CD, it may be better to imbue Burrow or Sandblast for immediate value.

Superior Duration

Superior Duration

Spirit T33,200 souls

Great item that synergyzes with Burrow, Combo and Scourge. This is a Defensive and Offensive Spike.

Transcendent Cooldown

Transcendent Cooldown

Spirit T46,400 souls

You can delay this for after Juggernaut/Scourge if you didn't buy Torment Pulse

ScourgeActive

Scourge

Spirit T46,400 souls

Use on yourself before using Combo, or use on an ally that is in a pinch. A very strong item if you have Trans. CD and duration. A solid first 6400 if you randomly have the money.

Buy if/when needed

Optional
3 items
Dispel MagicActive

Dispel Magic

Vitality T33,200 souls

Almost mandatory every game.

UnstoppableActive

Unstoppable

Vitality T46,400 souls

A good counter item to Dynamo if he keeps ulting your team. Very strong combo item with Cheat Death.

Reactive Barrier

Reactive Barrier

Vitality T21,600 souls

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

Late Game Common Options

Optional

Arctic BlastActive

Arctic Blast

Spirit T46,400 souls

Buy this to counter Indomitable

Spirit Resilience

Spirit Resilience

Vitality T33,200 souls

This is a very neccessary item almost every game because Mo is pretty vulnerable to spirit damage. Buy when needed, can be bought at any point in the game/build.

Phantom StrikeActive

Phantom Strike

Vitality T46,400 souls

A good item to buy the enemies are playing outside of Warp Stone+Dash Range constantly

Debuff Reducer

Debuff Reducer

Vitality T21,600 souls

This is now a very good item that is cheap and helps vs Crowd Control

Juggernaut

Vitality T46,400 souls

Feels like an every game item right now tbh

Cheat Death

Cheat Death

Vitality T46,400 souls

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. Beware of Capacitor, the active will remove this buff.

Metal SkinActive

Metal Skin

Vitality T33,200 souls

Very very strong into fed M1 carries, insane uptime with Sup. Duration and Trans. Cooldown when alternated with Burrow.

Bullet Resilience

Bullet Resilience

Vitality T33,200 souls

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.

Escalating Exposure

Escalating Exposure

Spirit T46,400 souls

The damage buff only works for you, and also a little resist.

Ethereal ShiftActive

Ethereal Shift

Spirit T46,400 souls
Diviner's Kevlar

Diviner's Kevlar

Vitality T46,400 souls

An item to buy if you are weaker and want your ults to be better. Cheaper, but worse, than getting Unstoppable and Cheat Death

Stamina Mastery

You might need this is Mina keeps breaking your legs with maxxed Love Bites

Quicksilver Reload

Quicksilver Reload

Spirit T21,600 soulsImbue

I believe this isn't as necessary every game now, still buyable if you need the extra healing

Guardian WardActive

Guardian Ward

Vitality T21,600 souls

Buffed item, pretty solid uses.

Divine BarrierActive

Divine Barrier

Vitality T46,400 souls

Counter item to build versus Pocket and Wraith, but generally a good item even without a specific counter

Cultist SacrificeActive

Cultist Sacrifice

Weapon T33,200 souls
Healing Booster

Healing Booster

Vitality T21,600 souls

Similar in value to Quicksilver Reload, but less damage and less healing depending on how much Anti-heal is on you

Heroic AuraActive

Heroic Aura

Weapon T33,200 souls
Fortitude

Fortitude

Vitality T33,200 souls

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

DecayActive

Decay

Spirit T33,200 souls

Newly buffed and does a very large amount of damage, though slowly. It is also the best anti-heal other than Spirit Burn

KnockdownActive

Knockdown

Spirit T33,200 souls

Very good item versus most heros, but Grey Talon, Lash, and Vindicta especially

Slowing HexActive

Slowing Hex

Can buy sooner if you need to splitpush for walkers. Throw on objectives, and on enemies before combo

Ballistic Enchantment

Ballistic Enchantment

Weapon T33,200 soulsImbue

If Krill's gun does get buffed at some point to being good, this will be a very good item to imbue onto Scorn

Magic Carpet

Spirit T46,400 souls

I believe this is a crutch item. But you do you.

Berserker

Berserker

Weapon T33,200 souls

Based on damage BEFORE resistances, so if you have a bunch of Bullet/Spirit Resist you will have max stacks constantly

Counterspell

Counterspell

Vitality T33,200 souls

Very, VERY strong item versus certain abilities like Lash, Shiv and Wraith ults. Unfortunately you cannot parry while burrowed or while channeling Combo

Mercurial Magnum

Mercurial Magnum

Spirit T46,400 souls

Buy this if you're out of slots or have nowhere else to spend your souls

Arcane Surge

Arcane Surge

Spirit T21,600 souls

This does not increase the damage or duration of Burrow. Pretty much only has value on Combo. Not a fan of the item.

Spirit Shielding

Spirit Shielding

Vitality T21,600 souls

This can be a life-saver in lanes like Viscous, Pocket, Geist, or Grey Talon, where they are very burst orriented. Delay monster rounds and sprint boots if you want this item.

Trophy Collector

Trophy Collector

Vitality T21,600 souls

Probably only good if you are very ahead, or you are behind AND your OTHER LANES are ahead. You must run around fighting pretty consistently to get value.
