Best early upgrade order

  • Damage % is one of the best first branches because it boosts your whole build immediately.
  • Crit Damage and Crit Chance are the next best combat branches once your base damage is online.
  • Luck matters a lot for long farming sessions, but it is also the most expensive branch to max.
  • HP % is still worth finishing later because late-game survivability checks get much harsher in Tower, Boss Rush, and harder dungeons.
