Predecessor Builds > Zinx > Raygun Zinx (The ONLY DPS Build) - Nin

I have tried several Zinx dps builds, and this is by far the strongest overall Zinx build for dps. With each item, Zinx scales very well. Not only does this build give great damage, and burst dmg autos with Oathkeeper (make sure to use this off CD in fights, cycle abilities properly with m1 after), but these items also give Zinx a very decent amount of health so she isn't that squishy. This build scales super hard in the late game, pretty decent midgame. Rush orb of growth into prophecy into worldbreaker t2 gem. From there you can complete worldbreaker. These 3 items are mandatory on her for this build - it is very gold-efficient, netting an extra ~100 magic power from the Worldbreaker passive, and Zinx's DoT on her basic attacks means the damage passive is stacked full permanently.

If you need anti-heal, grab tainted scepter t2 as your 4th item and then rush to buy Oathkeeper, completing tainted after as your 5th full item. If you are against tanky comp building magic armor, get Caustica t2 as 4th.

Disclaimer: Zinx is best played as support! Zinx mid can work and actually be quite effective; however, the majority of what she offers to her team is her useful CC, and well-utilized revives during teamfights. She performs best alongside a proper frontline. Will struggle more if team does not compose of bruiser + tank. Zinx isn't much of a carry in midlane though, at least difficult to pull off against decent opponents. Meaning, if there is a losing lane (especially duo) or jungler is struggling, the odds are stacked up against you. She is not as strong as traditional mages at burst/clear. Try to make mindful rotations and land those stuns to help your team secure kills. Zinx has potential if you play her strong suits well in Mid. Zinx pew-pew big dmg! If you are new to Zinx, I would practice her in support before trying this.

Tips: Play safe early, keep minions in the middle or pushed towards your side. Ward enemy jgl side around ~2:10 to avoid early gank. Use stun to shutdown enemy engage and follow up with E to slow. Rotate to support team when you can, try to 100% land the stun on gank. Be aware and avoid deaths, they are more punishing to Zinx than a regular midlaner. Skill Prio: R (ult) -> E (bad medicine) -> RMB (heal) -> Q (stun)
