Chapter 5 Walkthrough — The Abyss Beckons

Complete Chapter 5 walkthrough for Crimson Desert. The descent into the Abyss, Trukan the Ascended final boss, all side quests, hidden secrets, and the chapter's three endings explained.

Overview

Chapter 5 is the climactic descent into The Abyss — the ancient evil beneath Pywel that has haunted every chapter. Kliff and the Black Bears confront their final destiny in this 8–10 hour chapter featuring multiple endings based on your choices throughout the game. Chapter 5 is the longest single chapter and the point of no return for many companion quests.

By the time you reach the end of Chapter 5 you should be Level 45–52, wielding Tier 4 gear with at least one Tier 5 legendary, your Black Bears crew at full 10-member strength, and 3 of the 4 factions allied with you. The chapter culminates in the Trukan the Ascended final boss, after which you must make the game's ultimate dialogue choice: Sacrifice, Return, or Ascend. Each branch has very different epilogue content and unlocks different New Game+ bonuses.

Recommended pre-chapter setup: bring 30 healing potions, 20 mana potions, 15 stamina tonics, a Tier 4 main weapon with elemental mod, full Tier 3+ armor set, and at least 5 companion-bond items. This is the chapter where your accumulated reputation, companion loyalty, and gear matter most — Trukan cannot be brute-forced without proper preparation. Save before every dialogue node and before the Trukan fight — there is no going back once you enter the Abyss.

Chapter Walkthrough

5.1 — The Call of the Abyss: After Chapter 4 events, Kliff wakes to tremors across Pywel. Speak to Oongka at camp. Travel to the Demeniss border. Recommended Level 45+.

5.2 — Crossing the Threshold: Navigate through the Crumbling Pass. Defeat 3 elite demons guarding the entrance to the Abyss. Recommended Level 45+ with Tier 3 weapons.

Boss Strategy — Trukan the Ascended

Trukan the Ascended is the game's final boss and a 3-phase fight that tests every system you've learned. Recommended Level 48+ with Tier 4+ weapons and full Tier 3+ armor. He is a demon-human hybrid wielding a sentient greataxe and shadow magic. He has 4 elemental resistances and 1 weakness that rotates based on his mood — read his visual cues carefully.

Phase 1 (100%–60% HP) — The Ascendant: Trukan uses slow but devastating greataxe swings combined with shadow magic projectiles. The key tells are wind-up animations lasting ~1.2 seconds — perfect parry timing is just before the swing lands. He will occasionally chain into a 4-hit combo ending with a shadow explosion AoE; dodge sideways, not backward, as the AoE is wider than it looks. He summons 2 demon adds at 80% HP and again at 70% HP — prioritize them quickly so they do not pressure your stamina. Elemental weakness this phase: Fire.

Phase 2 (60%–30% HP) — The Shadow: At 60% HP, Trukan discards his greataxe and dual-wields shadow blades. He becomes much faster (attack speed +50%) but his damage per hit drops ~20%. The new mechanic is Shadow Clone — every 30 seconds he summons a mirror-image clone with 50% of his HP. Kill the clone first or you will be overwhelmed by 2 Trukans. Elemental weakness this phase: Holy (or Purify spell if you chose the magic path in Chapter 3).

Phase 3 (30%–0% HP) — The True Form: At 30% HP, Trukan transforms into his demon form — 12 feet tall, wings, and a breath attack. He gains +30% attack damage and +20% movement speed, but he also becomes vulnerable to stagger. The optimal strategy is to bait his opening breath attack, dodge behind him, then unleash a full stagger combo. He will attempt to flee at 10% HP and summon 3 elite demon adds — chase him with a sprinting heavy attack and use AoE to clear adds. Elemental weakness this phase: Lightning. Loot: Trukan's Greataxe (legendary, unique to this fight), Abyssal Heart (crafting material), 2000 Gold.

Hard Mode Tips: Bring 5 healing potions, 5 mana potions, max all food buffs, and the Crimson Reaper greatspear + Lightning enchantment. Have at least 2 companions active — Yann and Oongka are the strongest combo because Yann's parry window synergizes with Oongka's stagger combo. Speedrunners report sub-3-minute kills with full Tier 5 gear and the Bleed stacking build. If you chose the Sacrifice path in 5.10, Trukan's HP is reduced by 20% as a story reward.

Hidden Secrets

Chapter 5 has 8 hidden secrets including the most game-changing ones in the entire game.

Secret 1 — The Hidden Lake Cave: Beneath the Abyssal Lake, a hidden cave contains the Lake Dweller's Pearl (legendary accessory, +20% magic resistance).

Secret 2 — The Memory Vault's Secret: After collecting all 7 memory fragments, return to the Vault to find the 8th fragment — this unlocks the secret 'Witness' ending.

Secret 3 — Trukan's Regret: Before the final fight, speak to Trukan (a hidden dialogue option) to learn his backstory. This unlocks the 'Mercy' ending variant.

Secret 4 — The Crumbling Pass Wall: A breakable wall in the Pass reveals a hidden chamber with the Pass Ancient's Armor set.

Secret 5 — The Echo Chamber's True Recording: There are actually 6 recordings, not 5. The 6th is in a hidden alcove and unlocks the 'Truth Seeker' achievement.

Secret 6 — The Throne's Hidden Door: Behind the Throne, a secret door leads to a treasure room with the Abyssal Armor set.

Secret 7 — The Black Bears' Founder's Final Message: A hidden message from the Black Bears' founder, found only if you completed the Heritage quest in Chapter 4.

Secret 8 — The Sacrifice's Gift: If you choose the Sacrifice ending, Trukan's greataxe becomes a permanent equip with a unique effect (+10% all stats for the rest of the game).

Dialogue Choice Impact

Chapter 5 has 5 major dialogue choices. The final Choice E determines your ending.

Choice A — The Demeniss Border: Decide whether to evacuate civilians first or rush into the Abyss. Evacuate = +300 Refugee faction, slower start. Rush = faster start, but refugees die (visible scene, affects Ch6 NPC roster).

Choice B — The Memory Vault: After collecting the memory fragments, decide whether to share them with the party. Share = +500 XP for everyone. Keep secret = +1000 XP for Kliff but companions lose trust.

Choice C — The Pilgrim's March: Decide whether the Pilgrims join the descent. Yes = Pilgrim faction +400, but they die in the final battle. No = Pilgrims survive but you lose their support.

Choice D — Trukan's Humanity: Before the final fight, you can attempt to reach Trukan's human side (requires high reputation with Greymanes or completion of Greymanes quests). Success = Trukan has 20% less HP. Failure = Trukan enrages (+10% damage).

Choice E — THE FINAL CHOICE: Three options. (1) Sacrifice — Kliff sacrifices himself to seal the Abyss permanently. Unlocks 'Sacrifice' ending and 'Hero' achievement. Trukan's greataxe becomes permanent. (2) Return — Kliff returns to Pywel but the Abyss remains. Unlocks 'Return' ending and 'Survivor' achievement. Trukan's greataxe is lootable but not permanent. (3) Ascend — Kliff merges with the Abyss and becomes the new guardian. Unlocks 'Ascend' ending and 'Ascendant' achievement. Kliff becomes unplayable in NG+ but unlocks unique perks.

Chapter Endings Unlocked

Chapter 5 has 3 main endings and 6 hidden variants based on combination with prior chapter choices.

Ending 1 — The Sacrifice: Kliff sacrifices himself. Pywel is saved but you lose Kliff permanently. Unlocks the 'Sacrifice' achievement and the most powerful NG+ starting bonus.

Ending 2 — The Return: Kliff returns to Pywel but the Abyss remains a threat. Unlocks 'Return' achievement and a balanced NG+ starting bonus.

Ending 3 — The Ascend: Kliff becomes the new Abyss guardian. Unlocks 'Ascend' achievement and unique NG+ perks. Kliff is unplayable in NG+ but you can recruit his ghost.

Hidden Variant — The Witness: If you collected all 8 memory fragments (Secret 2), you unlock a 4th option during the final choice — Kliff becomes the eternal witness to history. Unlocks 'Witness' achievement and the 'Historian' NG+ perk.

Hidden Variant — The Mercy: If you spoke to Trukan's humanity (Secret 3), you can offer mercy instead of defeat. Trukan becomes an ally. Unlocks 'Mercy' achievement and the 'Demon Ally' NG+ perk.

Hidden Variant — The Truth Seeker: If you collected the 6th recording (Secret 5), you learn the ultimate truth about the Abyss. This unlocks the 'Truth Seeker' achievement and a hidden Ch6 questline.

Hidden Variant — The Balanced: If you combined balanced choices throughout Ch1-Ch5, you unlock a unique ending where all factions survive. Unlocks 'Balanced' achievement (rare, <3% of players get this).

Hidden Variant — The Lone Survivor: If all companions died by Chapter 5, Kliff faces the final boss alone. Unlocks 'Lone Survivor' achievement and a unique NG+ difficulty.

Hidden Variant — The True Ending: If you combined Sacrifice + Mercy + Witness, you unlock the 'True Ending' — Kliff, Trukan, and the Abyss are all reconciled. Unlocks 'True Ending' achievement (rarest, <1% of players get this).

Each ending has substantial Chapter 6 / NG+ differences. Plan your Chapter 5 playthrough carefully — your NG+ experience depends heavily on which ending you achieve here.
