I

猎怪弹

If the lane is very easy skip, otherwise sell for Alchemical Fire

I

额外充能

Never skip

I

灵力扩增

Easy damage, almost never skip

I

加强

秘术扩张

Never skip

I

疾跑靴

Do not rush this, grab if you're building Trophy Collector (you can get them whenever you want to gank or just for regen even)

III

寻猎季节

Back to being an option. I think Trophy Collector is still a good item for Ivy but you need to be more confident you'll be collecting stacks quickly - skip if the lane was bad

II

秘术缓速

Core part of your kit and great support - Lightning Scroll isn't a huge upgrade for you though

II

秘术脆弱

Probably the easiest way to help your team, and very useful for damage - upgrades into your best late item

II

主动

减速魔咒

You need it eventually Vortex Web, and very good for hitting Kudzu - particularly worth for [Infernus, Lash, Wraith, Dynamo, Calico, Abrams, Mina]

II

加强

冷却压缩

Imbue on 1 - Get this earlier if you're constantly running out (but this also means you're using Kudzu too often, save for fights)

III

火速充能

Only worth rushing earlier if you have Compress Cooldown already and have 2.4K but not 3.2K. Otherwise wait till you're done with Mid Core.

I

加速回复

Best for pure healing in lane, if you need it - sell whenever

I

主动

治疗仪式

If you or your lane partner are super low (like under 100hp) and you're happy to hide for 30 seconds

II

附魔纹章

Almost always useful - can swap for barrier instead. Needed for 4800.

II

秘术射击

Solid item, needed for 4800. If you skip consider Heroic Aura or Fleetfoot.

II

元灵压制

Good if they have more than one bullet carry (which is fairly common) - otherwise skip

II

减益缩短

Useful. Especially good if you need remover [Infernus, Shiv, Pocket, Mo & Krill]

III

主动

减益消除

Strong item especially for [Infernus, Shiv, Bebop, Seven, Warden, Vindicta]

I

秘术爆发

If you're feeling unsupported this can help win 1v1 and secure kills, upgrade later if they're tanky

III

重装克星

Really nice to have and now bypasses resistence! Get when they have 2.8-3K HP on more than one person.

II

不治魔咒

Good in most games [Geist, Mo & Krill, Dynamo, Kelvin, Calico, Abrams, Infernus, Pocket, Lash] can be sold for Spirit Burn. Skip if they have no healing or you need other optionals

II

应急屏障

Great item if you're in a lane that procs it

III

主动

炼金之火

I love Kudzu Bomb 2! BUT if you need loads of optionals (especially actives) or resists you can skip or sell later

II

灵力高涨

Easy, cheap upgrade - Skip this and sell Extra Spirit if you need space for more optionals

III

强效扩张

Great for your entire kit, BUT you can delay till you've started SCRAMBLING TIME if you're confident in your aim/timing - get as soon as you have Vortex or Spirit Burn at latest though

III

超速冷却

Good upgrade - now more important to upgrade again if you have actives (and if you don't have many you can delay this IF you're desperate for more damage

IV

伤上加伤

If you don't need movement control or better anti-heal, I think this is the best T4 to grab

IV

主动

雷织漩涡

If you need to lock their team down, particularly [Lash, Dynamo, Calico, Mina, Wraith] grab this as your first T4

IV

元灵燃烧

Get first (or even rush) if you're struggling to out damage the healing on their team, or they just have tons of it

IV

超凡冷却

This can be bought whenever really, but I think after V Web or Spirit Burn is fine, earlier if you have lots of optional actives

IV

雷鸣卷轴

It's a good item (and an upgrade so good for space) but lower priority that everything to the left, unless you need more ways to interupt as a team.

IV

灵力无边

This gives you lots more damage, but usually the game isn't going on long enough to afford this (and the rest of the build)

IV

主动

刷新环

Good item, LONG cooldown. Get Transcendent Cooldown first, and only worth getting earlier than other T4s if fights are very long, or it's going to be the last fight of the game

III

主动

天锤压顶

Needed against [Vindicta, Grey Talon, Seven and Ult Bebop], fairly good for [Lash, Dynamo] - fine in other games but usually something better

III

主动

沉默之潮

Great team impact against Spirit heavy teams, particularly helpful for [Mo & Krill, Bebop, Calico]

IV

主动

扰动

If one person on their team has all the souls, buy this

IV

主动

聚焦透镜

For focusing on one target very late game, once you have your first two/three T4s

IV

主动

身躯虚化

Excellent item, don't be put off by the cost it has good stats and amazing utility. Particularly good for [Lash, Shiv, Haze, Bebop, Burst Damage]

I

对等还击

Incredible item, but ONLY for [Viscous IF YOU CAN PARRY PUDDLE PUNCH, Very melee heavy lanes] - Buy this BEFORE LANE ENDS if you're getting it

III

法术反制

LOVE this against Lash, Infernus, Billy and a bunch of other counterable ults (Pocket if you've got good reaction speed)

II

主动

护卫结界

Got a nice buff and I feel worth considering now if you wanted to be supportive

IV

主动

神圣屏障

Got a nice buff and I feel worth considering now if you wanted to be supportive

III

主动

英雄光环

Really nice if you have bullet carries, or if they have a lot of bullet damage

IV

破阵之势

Best item here - particularly good paired with Bullet Resillience if you're still dying - also weirdly good against melee damage?

IV

铁板重甲

If you're getting killed by additional bullet effects this can be neccesary [Infernus & Haze] in particular

III

主动

铜皮铁骨

This is really just an anti-[Haze] item, and you can just stun her with Gargoyle unless she has unstoppable

III

元灵护体

Get if they're almost all Spirit and you keep dying. But your build has Spirit Resist already, so maybe just position better, dummy <3

IV

破咒护符

Buy for [Lash, Grey Talon] or other huge burst damage, or if you need more Debuff Resist

IV

主动

敌之灾患

Adaptable but takes practice - usually better to get something else or buy this to save your team's stronger people (if you're weak)
