I

Extra Regen

Pretty much need this for sustain, if you don't take a lot of damage the first two waves go Mystic Burst first

I

Imbue

Mystic Expansion

Kind of needed now with the bomb nerf

III

Radiant Regeneration

Completely nullifies the hp you spend on abilites, move speed is nice too

II

Kinetic Dash

Extra mobility, ammo and firerate

II

Opening Rounds

Weapon damage and spirit power, both good on Geist

II

Active

Return Fire

Kind of broken against m1s, skip if they don't have 2 or more

I

Active

Healing Rite

Break glass in case of emergency. I only buy this if something goes horribly wrong in the first few waves

I

Headshot Booster

If you're lane opponents have some big heads like Seven, Viscous, Ivy, Mo etc.

II

Active

Fleetfoot

Such a good item

III

Berserker

Big powerspike, you'll proc the full stacks on this in every fight

III

Active

Warp Stone

Really good for survivability and confirming swaps

III

Tankbuster

Can skip if your team already has a lot of spirit damage

IV

Spellslinger

Huge powerspike, once you get this just focus on tanking up

IV

Leech

You'll be doing tons of gun and spirit damage so this is a perfect item to stay in the fight

IV

Plated Armor

Buy earlier if they have a lot of m1s, can skip if they don't

II

Debuff Reducer

Buy and upgrade when needed (and you will probably need)

III

Spirit Resilience

You'll buy this at some point, try to get Spellslinger and Leech first though

III

Bullet Resilience

If they have a LOT of bullet damage, usually Return Fire, Fleetfoot and Berserker are plenty until super late game

IV

Juggernaut

Great stats against m1s if you need to go more tank heavy and they're already buying Armor Piercing

IV

Active

Colossus

Great item for Geist if you're trying to be more of a front line tank for your team

IV

Spellbreaker

Can be good against burst spirit damage heavy teams

IV

Healing Tempo

More fire rate and healing

IV

Siphon Bullets

True damage, more hp to tank with what's not to like

III

Toxic Bullets

Good antiheal option, really good in the late game

III

Weighted Shots

Good hybrid item for Geist and you won't really notice the downsides

IV

Crippling Headshot

You're doing tons of bullet and spirit damage so you'll benefit from both shreds

II

Healing Booster

Can be good sometimes, I usually don't think it's worth it though

II

Suppressor

Can buy if you want to go full anti m1s

IV

Armor Piercing Rounds

If they all start buying Plated Armor and Bullet Resist

IV

Cheat Death

Want to test this at some point for ultra late game, should theoretically prevent the main way you die in this build which is a CC chain not letting you get ult off
