  • Higher difficulty = stronger enemies but better loot drops
  • Stack multiple curse items across several runs
  • Part of the Holy Trinity meta build (requires Cursed Tome)
💡 Tips
Level up Cursed Tome naturally as part of your meta build. The difficulty increase is manageable and the extra loot is worth it. Cumulative stat tracked across all runs.

💡 Pro Tips for Basic Achievements

đŸŽ¯ Efficient Progression
Focus on multiple achievements per run. For example, work on tome upgrades while also aiming for survival and boss time achievements. This saves time and maximizes efficiency.
📚 Master the Holy Trinity
XP Tome + Cursed Tome + Luck Tome is the meta build. These three tomes make ALL achievements easier. Learn this build early and use it as your foundation. Note: It's "Cursed Tome" not "Curse Tome" - the official name includes the 'd'.
⚡ Character Selection
Fox and Sir Oofie are best for basic achievements. Fox for general progression, Sir Oofie for survival challenges. Both are available from the start and very beginner-friendly.
🔄 Practice Makes Perfect
Don't worry about failing. Each death teaches you enemy patterns and map layouts. The "Cursed Doll" achievement exists specifically to normalize failure as part of learning.
⏱ī¸ Soul Harvester Challenge
Soul Harvester requires a full 6 minutes of Final Swarm survival - not 5! This is one of the rarest achievements at ~8% unlock rate. The Kevin + Mirror combo is essential for the near-invincibility needed.
📊 Track Your Stats
Many achievements are cumulative across runs (Key, Cursed Doll, Skuleg). You don't need to complete them in a single run, so focus on steady progress over time.
