II

Infundir

Recarregamento Célere

I'm personally a fan of QSR and it can upgrade into magnum later. Can go active reload if you prefer but get 4800 spirit spike.

III

Balas Tóxicas

Good for anti heal and sustained damage. Combos well with ricochet.

II

Colete de Batalha

Can buy enchanters instead if enemy is spirit.

III

Ativa

Pedra Errática

I'm a huge warp stone fan, very good into lots of heroes. Can skip if you don't like for fort/other greens.

IV

Sanguessuga

Leech is extremely strong, you can go this very early if you are very ahead and want to start 1v6ing

IV

Ricochete

Buy when your damage feels good, extremely good for teamfights especially with leech.

IV

Tiro Debilitante na Cabeça

Good for damage/anti heal.

IV

Exposição Crescente

Gives good spirit resist, take that into account. Also good damge of course

II

Supressão

If enemy has several gun heroes I'd buy

II

Ativa

Feitiço Desacelerador

Huge fan of slowing hex if you're playing active at all. Good into so many heroes/items

III

Ativa

Onda Silenciadora

Slowing hex alternative, can be good since it shreds spirit

IV

Queima Espiritual

I don't really buy but if enemy has too much healing and you have slots/money

IV

Infundir

Magnum Mercurial

Very late game upgrade

II

Maldição Anticura

Can buy if you have tesla, dont get if you have toxic

III

Contrafeitiço

Can go this against certain ultis if you're being active. Wraith, holiday, etc

IV

Quebra-Magias

Good against some burst heroes, also gives debuff resist

III

Atravessador do Véu

Not a big veil fan, especially post nerf but you can buy

IV

Ativa

Irrefreável

Holy trinity is leech, ricochet, unstoppable for teamfights

IV

Ativa

Barreira Divina

I buy this sometimes against pocket, shorter cd than debuff remover and can be used on teammates.

II

Ativa

Pés Ligeiros

If you like fleetfoot and have slots, I personally don't go for it.

III

Rajada de Balas

Can get if you want more attack speed, good for burst and sliding

IV

Silenciador

Can buy if enemy has a ton of annoying casters, good with rico

IV

Transcendência Espiritual

I'd probably pick up other stuff for damage, also worse post nerf since doesn't provide duration.

IV

Ativa

Capacitor

Don't think you buy. Anti movement.

II

Balas Rompe-Espíritos

Can skip for bigger items, good though

III

Fenda Espiritual

Can skip for bigger items, good though

III

Resiliência

Possible buy instead of battle vest/spirit lifesteal/enduring.

I

Refutação

Don't usually buy unless they have a lot(really a lot) of melee

II

Proteção Balística

Hard to procc so I'd just go for spirit or reactive if you really need.
