What To Focus On For 100 Percent

Production and click milestones unlock early and scale naturally as you upgrade materials. Combat achievements require heavy grinding, especially Blood Lust VI, which demands 100 000 total kills.

Hemalith milestones require repeated rebirth cycles and long term accumulation. Familiar achievements require using, healing, losing, and collecting all available companions.

Gate and door achievements unlock through progression and exploration. If something seems mysterious, it probably unlocks by advancing deeper or meeting hidden requirements.

Reaching floor 1000 is a long term goal. Plan for optimization, rebirth bonuses, and strong Hemalith scaling before attempting deep runs.

Final Blurb

Horripilant achievements reward grinding, exploration, and long term scaling. Focus on boosting production, rebirthing wisely, collecting every familiar, and pushing floors steadily. The grind is real, but steady progress unlocks everything in time.
