I

Mystic Burst

Always first unless you NEED a regen item

I

Monster Rounds

You can swap for a vitality item, but the lane pressure here is excellent and it helps you farm

II

Arcane Surge

Cracked on Viscous. Dash jump before Splatter for lane poke, Cube for more regen, PP for a long range disrupt and always for Goo Ball

II

Enchanter's Emblem

Literally the best aspects of the old Spirit Armor and Enchanter's Barrier. Before Stamina is fine too

II

Imbue

Compress Cooldown

Always last in this section. Makes it so Goo Ball is always up for your rotations

I

Extra Health

Viscous does really well with health thanks to resists. This is more of a future setup item

I

Extra Regen

If you're getting lowish a lot, but you're currently at least half

I

Active

Healing Rite

If you're almost dead

III

Torment Pulse

I've been rushing this and it's really nice. Helps you farm faster, and still works before Goo Ball T5

III

Active

Warp Stone

If you don't build any extra T1s, you'll get this about 1600 souls after Goo Ball T5

III

Stamina Mastery

Don't sleep on Stamina Mastery. With Surge you have 6 stamina for 3 activations, crazy stamina recovery, good mobility and triple jump in Goo Ball

III

Fortitude

If you're feeling really squishy

III

Active

Debuff Remover

Honestly you could pretty much buy this every game, but it's especially good versus movement lockdown or silences. Seven, Warden, Vindicta come to mind

II

Healbane

Easy to apply with Torment Pulse, and that heal can be relevant. Antiheal still feels mandatory a lot of the time too

II

Spirit Shielding

Barrier scales with Goo Ball resists

II

Active

Return Fire

Return damage calculated before resists, so M1s will take equal damage to you in Goo Ball

II

Imbue

Duration Extender

Always buy unless you're slot locked (look for a T4 with duration tacked on)

III

Superior Duration

I get this most games -- 6% extra duration for Goo Ball, also nice for Cube. But make sure you buy this if you get Scourge

III

Tankbuster

Basically mandatory to do damage on Viscous late game

IV

Active

Scourge

So. Much. Damage. Also strong against Spirit comps. Harder if they have flyers though

IV

Active

Phantom Strike

Always get if they have more than 1 of: Seven, Bebop, Lash, Vindicta, Gray Talon. Disarm is also very good against Haze, Infernus, Wraith

III

Bullet Resilience

Reductive scaling means it's only 72%/84% in Goo Ball so only look for this if they are HEAVILY Bullet

III

Spirit Resilience

Reductive scaling means it's only 72%/84% in Goo Ball so only look for this if they are HEAVILY Spirit

III

Active

Decay

The damage is really good, but Healbane is much easier to apply AOE. I get this if they only have 1-2 problematic healers

III

Active

Knockdown

The only situation I would buy this over Phantom Strike is if you NEED it early and saving 6400 is not an option. Could be a second flyer hate item too

IV

Diviner's Kevlar

If you're TIGHT on slots you probably want this over Duration Extender because you're probably also getting shredded

IV

Witchmail

Love this item. Great versus Spirit heavy comps (but Scourge first usually)

IV

Plated Armor

The classic anti M1 item

IV

Spirit Burn

So good. It does SO MUCH damage and 70% antiheal is insane. If you're ahead and want to snowball you could buy this as your first T4

IV

Boundless Spirit

Raw damage bump. Great for Viscous. Pairs nicely with Spirit Burn too

IV

Active

Magic Carpet

I think this item might be slept on. I would buy it more if Phantom Strike wasn't so damn good. The bonus stats are awesome and you can use it for mobility too

II

Improved Spirit

I built this in lane for a long time, but I've found that your tower is usually down by 7000 or so souls and in that time I'd rather have Arcane Surge and Enchanter's Emblem

II

Active

Cold Front

It just feels underwhelming to me most of the time. I'd generally just rather save up and get an early Torment Pulse

III

Greater Expansion

On paper Ability Range should be really good for Viscous. In practice though it makes Goo Ball basically unusuable in small rooms and it fucks up your Warp Stone distance
