This thread is for thoughts and discussion on Cobalt.

Based on preferences Forum members have expressed, please try to stick mainly to Cobalt and not wander off topic too much to other heroes.

Some Popular Questions for Discussion

  • Is Cobalt worth summoning for?

  • Would you use Cobalt on Defense? Offense? War? Quests/Events? Titans?

  • Which heroes on your Roster best pair with Cobalt ?

  • What heroes would you take when facing Cobalt as an opponent?

  • Would you give Cobalt Wizard Emblems? Which Talent Grid path will you choose?

*NOTE: Summon Results posted without any commentary/feedback at all should be flagged as Off Topic and removed, based on preferences expressed by the Forum community. Please include some comments about what you think of Cobalt when posting Summon Results. In addition to opinions about Cobalt, you are also encouraged to include how many Summons it took before receiving Cobalt (or how many Summons you’ve done without receiving Cobalt), so other players are presented with realistic experiences of the rarity of Legendary Event Hero.

:money_with_wings: Avoiding Overspending & Heartache :broken_heart:
Or: How many summons are needed to get a Legendary Challenge Event Hero?

It’s important to remember that Challenge Event Heroes have EXTREMELY low summoning odds. No amount of summoning will guarantee a Challenge Event Hero.

On average, in a 10-pull, you have a 1.65% chance of summoning Cobalt.

But that statistic can lead our minds astray in exactly how our odds play out as we continue summoning.

Some useful insights:

  • 15 times out of 100, you’ll get Cobalt by pull 100 (26,000 gems)
  • 56 times out of 100, you’ll get Cobalt by pull 500 (130,000 gems)
  • 95 times out of 100, you’ll get Cobalt by pull 1,796 (467,200 gems)
  • 99 times out of 100, you’ll get Cobalt by pull 2,761 (717,900 gems)

Putting that in Perspective

  • 85 out of every 100 people won’t get Cobalt by the 100th pull

  • If 1 Million players each spent $259.97 (US) to summon :one::zero::zero: times, 846,364 of those players wouldn’t get Cobalt

  • 5 out of every 100 people won’t get Cobalt by the 1800th pull

  • If 1 Million players each spent $4,671.53 US to summon :one::eight::zero::zero: times, 49,663 of those players wouldn’t get Cobalt

More Insights & Reading

I highly recommend reading these three threads for more information and context on summoning odds:

If you’ve read them a million times before, you may consider reading them again before deciding on your budget for summoning. A little time spent deciding on how much money you want to risk on summoning goes a long way to avoiding disappointment, frustration, and regret later. :slight_smile:

Poor cobalt, officially outclassed by ruby. So of course I got him instead of her


I got Cobalt as well. He may be slightly outclassed by Ruby, but he’s still an overall solid hero. I nearly ha e him maxed out

Too many blue projects, too little emblems for him. Back he goes in line :dizzy_face:

Got him as well.

Ruby maybe outclasses him but I have lack of blue attackers so he’ll serve me well. And he’s still powerful. Ruby may cripple enemies but Cobalt will kill them outright with his bypass and possible Jinx talent trigger. And with Onyx he’ll have that tasty family bonus.


you’ll love Cobalt. I already maxed him.


I have a question. Do Cobalt x3 charge always bypass C Kadilen/Inari dodge and Margaret/Jade dodge ?

He don’t, dodge skill isn’t consider a def buff


Really, dodge isn’t defensive buff. Could you post a picture ?

I don’t have a picture but @Grajek is right. C Kad’s dodge works against Cobalt. I have both, use them regularly.


I initially thought that it was a bug and opened a thread, here we go:
