I

近战火拼

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

加速回血

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

额外充能

Great for poke and for heals (at 2.6k)

I

秘术爆发

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

II

附魔纹章

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

I

加强

秘术扩张

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

II

加强

冷却压缩

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

II

主动

护卫结界

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

猎怪弹

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

I

主动

治疗仪式

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

I

疗愈子弹

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

治疗强化

Insanely strong item on Kelvin, buy this every game.

III

主动

营救光束

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

超速冷却

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

余威久久

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

强效扩张

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

超凡冷却

Buy when locked for slots or have 3+ actives

IV

治疗律动

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

主动

轻盈飞步

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

II

疾速不怠

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

III

主动

传送石

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

主动

英雄光环

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

主动

炼金之火

Been experimenting with this more when wanting to deal more damage

III

主动

治疗之环

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

主动

神圣屏障

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

主动

技能刷新

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

II

主动

减速魔咒

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

主动

天锤压顶

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

III

主动

缴械魔咒

Very situational item, save up for curse if possible.

IV

主动

诅咒

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

重装克星

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

火速充能

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

II

不治魔咒

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

II

元灵压制

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

II

秘术脆弱

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

粉碎护甲

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

III

猎人光环

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

III

灵力不催

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

III

枪弹不催

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

IV

铁板重甲

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

制敌凌威

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

III

法术反制

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

IV

主动

势不可挡

Main use is against Dynamo, ideally use Counterspell instead.
