Even while sparks are more useful for farming, Flux is much more useful for killing people (double flux = 100% slow or 100 ms on targeted hero and a lot of damage), so you want to max out it first
Our strongest spell for both offensive (a lot of bonus attack speed) and defensive (save allies, yourself or even your base from being attacked) plays, altho not really useful for killing early on
We can spam it with octarine and aquila, it can help us out in lane so we won&apos;t get ganked, RQQEE combo will kill almost anybody in early game
Your main trick. With double you can instakill a lot of heroes, splitfarm and be quite useful in fights. Just remember that you need as much effective slots (active items you can use twice or use without losing charges) as possible to get maximum value out of it
Arc Warden&apos;s signature farming tool. Can be skipped if you are behind
Maelstrom is already good enough for your hero, considering having a lot of attack speed, but also increases farming a lot (magnetic field + maelstrom almost completely kills creepwave)
Gives us ability to split-farm and join the fights from far away. And, of course, increases our mobility even further, so you don&apos;t need to care about movement speed anymore
ALTERNATIVE: Power Treads
Works with Tempest Magnetic Field
Increase in our farming speed and huge boost to our damage in fights. Maelstrom is pretty good to get early by itself, but early mjolnir is even better if you&apos;re going to participate in fights by yourself
Works great in combination with Manta. Essentially provides cheap damage and additional crowd control
Gleipnir costs a bit more than Mjolnir and provides less DPS, but it provides a valuable utility in return, allowing you to clear creep waves faster and pick off heroes more reliably.
You can get it before maelstrom if you&apos;re afraid of dying. Generally a good item for Arc, that allowes you to initiate on somebody off-guard with double.
ALTERNATIVES: Hurricane Pike, Blink Dagger
Good for initiating from long range with hex and preventing enemy from reacting.
ALTERNATIVES: Hurricane Pike, Shadow Blade
Stat boost and additional escape for cases when something goes wrong (can be used offensively too). Very good against gap closers (PA, Clockwerk, Riki)
ALTERNATIVES: Shadow Blade, Blink Dagger
Additional lockdown, one of the best lategame items for Arc since you have not one, but two hexes. It can be replaced with Bloodthorn+nullifier combo, but hex is better since it cannot be dispelled (while nullifier+bloodthorn combo can be purged with everything)
High attack speed inside of magnetic field, a lot of potential procs
It may turn you into walking tank. Altho, you will have low damage output and won&apos;t be able to use properly all of you slots (considering two of them being octarine and BoTs already, you will have only three effective slots)
High damage increase and tankiness from miss chance. It&apos;s cheap enough so we can continue our pressure, while also providing decent damage against towers.
Good when paired with Bloodthorn, but the projectile is quite slow so most of the time you won&apos;t be able to get it out in time
Offensive lockdown solution. It can be purged so it&apos;s more of a DPS/focus item, but can be rushed early via Orchid to snowball or kill targets faster in the lategame
If you are going to join fights early and be in epicenter of them, you should probably get BKB most of the time, usually against heroes with high magic damage or controlling spells. Don&apos;t be afraid to get it early and use it every time: it will pay off sooner than you think
Other Significant Items
Since we are tanky enough, it&apos;s good to stop enemies from trying to bring us down or at least deal reasonable amounts of damage to them
