I

Tir rapproché

Incredibly soul efficient item. Early game, your gun does quite a bit more damage than your beam, and close quarters always amplifies it. Can keep until slot locked, or even longer if enemy is melee.

I

Bonus de régénération

I buy this frequently in lane, especially after the slight Resto Shot nerfs. Can be substituted with Healing Rite if you are especially low.

I

Charge bonus

Great for poke and for heals (at 2.6k)

I

Choc mystique

Been liking this over QSR due to the buff to Tankbuster.

II

Emblème enchanteur

If you can afford to live until 1600 in a spirit heavy lane, this is a great option. Must buy every game.

I

Imprégner

Expansion mystique

This allows for much more consistent domes. Aim to isolate 2v1s with your dome.

II

Imprégner

Récupération comprimée

Getting more frequent domes allows you to be more efficient/effective on the map, and take advantageous fights.

II

Active

Sentinelle gardienne

Great against Bebop, Lash, Pocket, or any form of burst damage. Especially good if there is a pocket on the team in general, as you can upgrade it to Divine Barrier.

I

Balles antimonstres

If you are in a stall lane and need to clear wave easier, monster rounds is a great option.

I

Active

Rite de guérison

Buy every game, sooner or later. Can buy earlier in lane if especially low.

I

Tir curatif

If used correctly, gives the strongest consistent source of regen you can get early. However, this is difficult to use on Kelvin due to his low bullet velocity. Also 6% weapon dmg cuz wtf

II

Amplisoins

Insanely strong item on Kelvin, buy this every game.

III

Active

Faisceau de détresse

Always buy this item, it's simply too good. Buy early if going against a Bebop, Holliday, Paradox, Mo & Krill, Lash, etc. Can afford to delay if there's no pick on enemy team.

III

Récupération supérieure

Been experimenting buying this later since Transcendent Cooldown was released. It's still a very strong item on Kelvin, but can afford to delay after you get some utility.

III

Prolongation supérieure

Will rarely buy this item, unless you have multiple actives that rely on duration (primarily curse, also includes Heroic Aura, Divine Barrier, Slowing Hex, etc.)

III

Expansion supérieure

Will primarily buy this if slot locked or need larger range on items (especially Rescue Beam). Remember, though, that it becomes more difficult to isolate small fights the bigger your dome is.

IV

Récupération transcendante

Buy when locked for slots or have 3+ actives

IV

Tempo curatif

Been buying this less and less, still very strong when you have 2-3+ M1 carries. The stats are very potent, the issue becomes keeping it applied to multiple people

II

Active

Pied plume

Really strong tempo buy on Kelvin can buy instead or in conjunction with Enduring Speed.

II

Vitesse persistante

Very strong item that allows for quick rotations; also allows for faster movement in a teamfight

III

Active

Pierre de distorsion

Warp Stone is an underbought item on Kelvin, with many practical uses throughout the map. Quite strong against characters like Lash and Haze, or if needing a quick dome by using Warp Stone -> Dome

III

Active

Aura héroïque

Insanely strong item to support your M1 carries or if the enemy team has significant gun damage. This also gives 2m/s sprint speed for some odd reason (Yoshi?)

III

Active

Pyroalchimie

Been experimenting with this more when wanting to deal more damage

III

Active

Nova curative

Not always necessary, but I have been buying this more and more simply due to how strong it is for team heals. Often my 2nd or 3rd highest healing source when I buy it.

IV

Active

Protection divine

Insanely strong counter to Pocket, but I have saved people a countless number of times, especially when the enemy team have lots of DoT or debuffs.

IV

Active

Rembobineur

Would recommend buying this right before or even after you buy Transcendent Cooldown. Strong against Lash ult, or in sustained fights.

II

Active

Malédiction de ralentissement

Strong into any characters with movement abilities (over half of the roster), and even those without, as the dash distance reduction really hinders movement.

III

Active

Coup d'enclume

Great against Seven, Lash, Vindicta, Ivy, Grey Talon, Mo & Krill (when stunned out of burrow, he just dies), Bebop, and Dynamo

III

Active

Malédiction désarmante

Very situational item, save up for curse if possible.

IV

Active

Malédiction

Great against strong teamfight channel ults (Dynamo, Lash, Bebop, Haze, McGinnis, Warden during his channel (hand up) phase), and also to shut down carries (it really screws Pocket, for example, over)

III

Antichar

Very strong ever since the pure damage buff. A great option if you feel that your team is lacking spirit damage. Buy only after max nade

III

Recharge rapide

Buy if you are either slot locked, have max nade, or need more consistent heals.

II

Châtiment curatif

Fantastic item, especially necessary against characters like Warden, Abrams, Dynamo, and Mo & Krill.

II

Sabotage

Can buy in lane against 2 m1s, simply buy if they have gun carries.

II

Vulnérabilité mystique

Unfortunately weak shred in comparison to it's bullet resist shred counterparts. Ideally you have someone like a Vin or a Seven who can apply this, or an m1 who buys Spirit Rend.

II

Balles perforantes

Very strong if you have multiple gun carries, and is nice if duo'd with a gun/melee character.

III

Aura prédatrice

Really strong if isolating people in domes with your gun/melee characters (they will literally explode with -24% bullet resist). Underbought item

III

Résilience spirituelle

Along with Counterspell, this is your primary method to combat Spirit Damage (unless you can save up for Counterspell I suppose)

III

Résilience balistique

Rare buy, as Plated Armor and Juggernaut are both better options to save up for.

IV

Armure de plates

Especially strong against on hit characters (Infernus afterburn, Haze fixation, Seven power surge, etc.) or against on hit items (e.g. Lucky Shot or Tesla Bullets).

IV

Implacable

Can buy as an upgrade to Enduring Speed if lacking slots, very strong against both Gun carries and Melee characters.

III

Contresort

Great against Lash, Geist, Shiv, and CC heavy comps.

IV

Active

Intouchable

Main use is against Dynamo, ideally use Counterspell instead.
