II

Imbuir

Recarga Repentina

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

Chaleco de Batalla

Can buy enchanters instead if enemy is spirit.

III

Activo

Piedra de Teletransporte

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

Sanguijuela

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

IV

Rebote

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

IV

Disparo Paralizante a la Cabeza

Good for damage/anti heal.

IV

Exposición Creciente

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

II

Supresor

If enemy has several gun heroes I'd buy

II

Activo

Hechizo Ralentizante

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

III

Activo

Ola de Silencio

Slowing hex alternative, can be good since it shreds spirit

IV

Quemadura Espiritual

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

IV

Imbuir

Magnum Mercurial

Very late game upgrade

II

Maleficio Anticuración

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

III

Contrahechizo

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

IV

Rompehechizos

Good against some burst heroes, also gives debuff resist

III

Caminante del Velo

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

IV

Activo

Imparable

Holy trinity is leech, ricochet, unstoppable for teamfights

IV

Activo

Barrera Divina

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

II

Activo

Pies Ligeros

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

III

Fuego a Discreción

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

Desbordamiento Espiritual

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

IV

Activo

Condensador

Don't think you buy. Anti movement.

II

Balas Machacaespíritus

Can skip for bigger items, good though

III

Desgarro Espiritual

Can skip for bigger items, good though

III

Fortaleza

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

I

Refutación

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

II

Protección Balística

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