How to reach Degree 100 (solo)

In solo play the four standard power categories top out below Degree 100, so a maxed Crucible of Steel and Flame needs Geraldo's Paragon Power Totems to close the gap. The most cash-efficient solo path on Medium difficulty:

  • 16,200,000 equivalent pops/damage (income counts as 4 pops per $1)
  • 100 sacrificed upgrade tiers
  • $600,000 spent on sacrificed towers
  • 20 Geraldo Paragon Power Totems

Co-op is cheaper: each player can sacrifice extra Tier 5s, which cuts the totems you need. Adjust the target degree, difficulty and game mode in the calculator.
