Hello! This is a guide to get you through the Cosmic Trial with Black Cat. Note: This is NOT the best Black Cat. It is NOT end game Black Cat. You will not find the BiS items in this build. 

Set Up

I capped myself at 150 Infinity Points for these trial guides. It won't take too long to build up that many. By the time you've leveled up a few characters for synergies and farmed some Heroic (Red) Challenges and terminals for some gear you may even be past 150 IP when you try the trial. Worst thing that can happen when you try the trial is you fail there is no punishment. So give it a shot and see if you're missing damage, survivability or both.

Not all end game builds work equally well with less IP and gear. I tried a couple of the builds that already existed and found one that worked well to get through the Cosmic Trial. Black Cat cleared pretty easily with a minute to spare on both Madame Hydra and Red Skull - she wiped out the minions super fast but slowed down on the bosses a bit. She was never in danger of losing one life let alone all 9.

 

Synergies

Angela, Cable, Elektra, Hulk, Moon Knight, Nightcrawler, Squirrel Girl, War Machine, Wolverine, X-23

Infinities

Alot of times my first go to with Infinities is the attack and movement speed node (Remilla does a great job explaining attack speed and the infinity system @RemiFromMH on YT) in the Time Stone - (Temporal Loophole). 

Gear

I ended up using  it's a great damage option for most heroes.

Black Cat's Slot 1-5 will work just fine for clearing the trial. 

When you're gearing you may have to make a choice between FIGHTING and SPEED attributes. Always choose FIGHTING. 

    are all pretty easy to find artifacts that will give nice stats for Black Cat.

The only other Artifact really worth mentioning is the . I did not have one when I did this trial. If you do swap it in. It applies vulnerable when you use your signature. There is no other way to apply vulnerable in this build. 

Team Up

I used Jessica Jones for my team up because I liked the way she groups enemies up for me to jump on.

 

Playstyle

The first thing you need to wrap your head around for Black Cat is that she does not generate spirit. Her  gives you a small spirit regen. Finding a Catalyst that has spirit regen on med kit use could help alot. If you find one use your Medkit on CD to get spirit back. Remember your bleeds last for a duration so you dont need to spam them. You can coserve some spirit this way if you need to.

The other cool mechanic for Black Cat is her 9 lives. You have 9 cheat deaths. You will come back to life w/ a small amount of health bar - so if you see yourself go down get out of danger quick so you can regen back up. I've lost multiple lives in a row not paying attention. 

Our first row talent is also worth noting. It gives a bonus +2% to crit and brutal chance. It also gives a 2% chance on hit to kill a non boss enemy instantly. Everyone of the shield minions got killed off by this passive for me. I assume it has the chance to trigger off dots as well as attacks - which there's a bunch of instances of damage hitting at once for Cat. Either that and/or I got extremely lucky.

 does more damage than . But it consumes spirit. If you are having spirit issues and medkit isn't enough you could also swap your left click from    to      - It doesn't build spirit but it doesn't spend any either. 

 - We're going to use this on CD. It buffs all our claw damage for 5s and when it is on CD our  get a buff as well.

 - A jump - so you can use it to get onto enemies. A bit of area and it applies a bleed. You want to have all 3 of your bleeds up as much as possible.

 - A movement ability where Cat spins and applies a bleed to enemies she hits. Our 3rd bleed. Also what I used to reposition and move about most of the time. I did not put her  on my bar. So there is no CC break in this build. If you are having issues avoiding damage swap these two.

- Our fourth row talent turns our signature into The Cat's Meow. Its a large aoe that does a ton of damage. Also remember if you have  it will apply vulnerable to our enemies. We want to use this early in fights to maximize our damage.

- Will stealth you. Buffs your damage and restores some spirit. Also makes it so you steal loot periodically. Not like loot for you character, small treasures you can sell to a vendor for credits.

 - Until you get your last row talent this can only be used from Stealth. After getting the talent at lvl 56 you don't need to be stealthed to use it anymore which makes it alot easier to use. Our 2nd bleed and our strongest bleed. You definitely want to make sure this one is up all the time.

Start with your signature (especially on the bosses) stay on the move and keep your bleeds up. Even if you make some missteps and take damage you didn't mean to, or should have dodged and she goes down you have 9 lives.

Hopefully this helps you clear the Cosmic Trial so that you can start farming your best gear and move on to bigger and better content and bigger and better guides! Have fun out there.

Thanks!
