How can I get an Inspiration Talisman?

[Firehead]

Some of the recent event challenges are winning gauntlet matches with certain talismans equipped to characters. I have all the ones needed except for the 2-piece Inspiration set. For one reason I do have one Inspiration talisman, but now I need another. Is there anywhere where Inspiration talismans drop?

They drop on viral dungeon, very rarely.

Only on the Madness stage. They're not as rare as most other dungeon drop talismans, I'd be very surprised it it took you more than two keys (30 runs) to complete your set. You'll probably only need one key. Best of luck!
