BLACK SOULS Achievement Guide — All 65 Achievements

BLACK SOULS’ achievement list is beautifully blunt: 51 bosses, 14 endings, nothing else. No “open 100 chests,” no grind markers. 100% means you have seen everything the Lost Empire does to its fairy tales. Track your progress in the Achievement Tracker, which carries this full list with live rarity.

The shape of the list

• 51 boss achievements — one per tracked encounter, including the Helkaiser rematches. They range from 56.4% (Drake Helkaiser) down to 11.4% (Saint Catherine), falling in a smooth curve that mirrors progression. The boss order guide walks the whole curve.
• 14 ending achievements — four lettered, ten character. Endings are the schedule constraint: each cycle produces at most one lettered ending plus whatever character endings you finished. The routing math lives in the endings guide.

The efficient 100% plan

1. Cycles 1–2: volume. Clear every boss you naturally reach and take B End, then C or D. By the end of cycle two you should hold roughly the top 35 boss achievements without trying.
2. Cycles 3–4: routes. Character endings in batches, per the recruitment guide. Each route drags its linked boss along: Victoria brings Demon of Desire (20%), Elisabeth brings the Torture Queen (18.3%), Goose brings the Golden Goose (14%).
3. Final cycles: the rare shelf. A End (21.1%), then the deep fights: the Cursed Siblings (15.2% / 14.1%), Little Match Girl (13.7%), Holy Beast Jeanne d’Arc (12.1%), Saint Catherine (11.4%). Do these on your most developed character — they are the reason your build exists.

Milestones worth knowing

Practical notes

• Nothing is missable forever. Everything reopens in New Game+; “missable” in BLACK SOULS always means “missable this cycle.”
• Boss achievements pop on the kill, ending achievements on the credits. If you’re cycle-planning, count endings — bosses accumulate on their own.
• Below ~20% rarity, stop treating fights as walls and start treating them as routes. You reach them by following a character’s story, not by wandering into them.
