💡 Pro Tip

Always prioritize Limit Break if you have any strength gain. Doubling your strength is the most efficient damage scaling in the game. Pair with Heavy Blade for one-shot potential.

🗡️ Silent

The Silent is a dexterity and poison-based character with 70 HP. She excels at defensive play through weak/vulnerable debuffs and scales damage through poison or shiv generation.

💡 Pro Tip

Poison builds are the most consistent for Ascension. Catalyst triples poison — getting two Catalysts means 9x poison multiplier. Always take Noxious Fumes as your first power.

⚡ Defect

The Defect is an orb-based character with 75 HP. He channels lightning, frost, and plasma orbs to deal damage, block, and generate energy. The most complex character with the highest skill ceiling.

💡 Pro Tip

Enter Wrath only when you can kill or have enough block. The 2x damage taken is deadly against multi-hit enemies. Rushdown is your best friend for infinite stance dancing.

📋 General Character Tips

  • Always remove Strikes before Defends (except Silent)
  • Prioritize campfire upgrades over resting in Act 1
  • Take elite fights in Act 1 for relics — you need the power spike
  • Don't take every card offered — a thin deck is better than a thick deck
  • Shop priority: Remove card > Rare relic > Key card > Potion
  • Aim for 25-35 cards in final deck (excluding curses)
