Archdemon: How to deal 1B damage

Presentation

Adam alone against the Archdemon

  • The Archdemon is found at the end of any chapter of the event

  • You can fight him as much as you want, but you need to restart and complete a chapter every time

  • The buffs you buy from the workshop also count for this fight

  • You get a chapter-specific damage multiplier (10% - 100%): the higher the chapter, the higher the bonus

  • The fifty highest scorers earn between 200 and 30k emeralds. The latter certainly look nice, but you would need to spend way more money than they are worth for.

How to achieve 1B in ten minutes

  • Get at least 100 buffs, preferably 150

  • Go to chapter IV (for meta team and enough buffs)

  • Restart until you get the attack-only talisman

  • Use one of the two teams below. All 7/7, same pets, the slightest change will alter the results

  • Kayla variant is slightly better, but not that important: Isaac is the real star of the show

How to achieve 17B

  • You must have 270 buffs. Not 300, just 270. Maybe the random generator seed is fixed and this is what gives the highest crit rate?

  • Kayla and Guus must be 3/7. Maybe to let Kayla ult more and give more artifact buffs? As for Guus, I have no idea: do hero levels change the seed?

  • This is the best combo found so far, there may be an even better way

  • Big thanks to Jester for his help

Teams

The damage indicated below are anecdotal and can greatly vary with very slight changes. I assume the rng seed is fixed and change with your set-up.
