Divinity: Original Sin 2 Walkthrough — Start to Endgame

Divinity: Original Sin 2 is widely considered one of the greatest CRPGs ever made, blending deep tactical turn-based combat with systemic environmental interactions and genuine narrative freedom. The surface combo system lets you set oil on fire, electrify water, freeze blood pools, and chain elemental reactions in creative ways the developers never intended. With 4-player co-op campaign support and a GM mode for creating custom adventures, DOS2 offers hundreds of hours of content. The Definitive Edition added a full Act 3 rework, improved tutorials, and thousands of new voice lines.

This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. Follow this path to avoid common traps that stall most players.

Quick Progression Summary

Phase 1: Getting Started — Fort Joy

The starting area (Act 1) where you're imprisoned on a Sourcerer island. The area teaches core mechanics through a relatively contained space with multiple escape routes. Major decisions here affect the entire game — which companion you recruit, how you escape, and who you ally with.

Level/Difficulty: Levels 1-9 Key Rewards: Companion recruitment, first Source point, teleportation gloves, Fane's face ripper

What to Do in Fort Joy

1. Learn surface combos. Surfaces are created by spells and environmental effects: fire creates burning ground, rain creates water puddles, oil is flammable, blood can be frozen or electrified. Spend your first session getting comfortable with this.
2. Pick Necromancer as your starting build. It's the most forgiving option.
3. The respec mirror on the Lady Vengeance lets you completely rebuild any character for free — change attributes, abilities, talents, and even appearance at any time. Use it constantly to experiment with builds.
4. Acquire your first equipment upgrade — Falone Scythe or whatever's available.
5. Clear all main content before moving on.

Phase 1 Checklist

• Understand surface combos fundamentals
• Necromancer selected and functional
• Fort Joy main content cleared
• Ready for Reaper's Coast

Phase 2: Early Game — Reaper's Coast

A large open region (Act 2) with the town of Driftwood as its hub. The most content-dense act with dozens of quests, four Source Masters to find, and multiple faction storylines. Level scaling ranges from 9-16, so exploration order matters. The Blackpits oil field and Mordus questline are highlights.

Level/Difficulty: Levels 9-16 Key Rewards: Source point capacity increase (up to 3), powerful gear, extensive side quests

What to Do in Reaper's Coast

1. Work on initiative system. Turn order is determined by Initiative stat (Wits attribute + gear bonuses). This system becomes critical from here on.
2. Farm for Falone Scythe if you haven't already. It's the key upgrade for this phase.
3. Teleport (Aerotheurge 2) is the single most powerful skill in the game. It repositions enemies into hazards, groups them for AoE, moves allies out of danger, and solves environmental puzzles. Every party needs at least one character with it.
4. Complete all objectives before pushing to Nameless Isle.
5. Consider whether Lone Wolf might suit your playstyle better than Necromancer.

Phase 2 Checklist

• initiative system integrated into gameplay
• Falone Scythe acquired
• Reaper's Coast fully cleared
• Ready for Nameless Isle

Phase 3: Mid Game — Nameless Isle

A contested island (Act 3) where all Godwoken race to claim divinity. Shorter than Act 2 but dense with difficult combat encounters. The Academy puzzle is the centerpiece. Multiple factions compete here and your choices determine who reaches the Well of Ascension.

Level/Difficulty: Levels 16-18 Key Rewards: Swornbreaker, eternal artifacts, Academy rewards, path to divinity

What to Do in Nameless Isle

1. Master civil abilities. Non-combat skills that affect dialogue and exploration: Persuasion (conversation options), Lucky Charm (random loot quality), Thievery (pickpocketing and lockpicking), Loremaster (identifying items), and Bartering (shop prices). This unlocks a new layer of gameplay.
2. Start working toward Anathema. It's the best equipment and becomes accessible around now.
3. Focus your entire party on either physical or magic damage. Mixed damage parties struggle because enemies have separate armor types — you need to strip one type completely before CC works.
4. This area is the main skill check. If you can clear it, you're ready for late game.
5. Start investing in Source points for the tactical depth you'll need going forward.

Phase 3 Checklist

• civil abilities mastered
• Anathema acquired or in progress
• Nameless Isle fully cleared
• Ready for Arx

Phase 4: Late Game — Arx

The final city (Act 4) under siege by Voidwoken. Contains the climactic story sequences and hardest combat encounters. Magister's Cathedral, Kemm's vault, and the Doctor's house are major locations. The Anathema sword and endgame gear are found here.

Level/Difficulty: Levels 18-21 Key Rewards: Anathema, endgame gear, final story resolutions, ultimate abilities

What to Do in Arx

1. Finalize your build. You should be running Lone Wolf or Necromancer with optimized gear.
2. Anathema should be your primary. If you don't have it yet, prioritize getting it.
3. Thievery is incredibly powerful — pickpocket every merchant before buying from them to get items for free. Each character can pickpocket a merchant once, so cycle all party members through each vendor.
4. armor system optimization starts here. Small improvements compound into massive advantages.
5. Farm this area for the resources needed to push into Lady Vengeance.

Phase 4 Checklist

• Build fully optimized
• Anathema upgraded to max
• Arx fully cleared
• Ready for Lady Vengeance

Phase 5: Endgame — Lady Vengeance

Your ship that serves as a mobile base between acts. The ship contains a mirror for free respec (unlimited stat/skill resets), storage, and party management. Use the respec mirror freely to experiment with builds — there's no cost or penalty.

Level/Difficulty: Acts 2-4 Key Rewards: Free respec mirror, party management, storage, rest/heal

What to Do in Lady Vengeance

1. Lady Vengeance tests everything. Come prepared with your best build and gear.
2. Pet Pal talent lets you talk to animals, unlocking hidden quests, treasure locations, and world-building dialogue. Give it to your main character for dozens of additional quest lines and secret information.
3. The endgame loop: run Lady Vengeance, optimize gear, push harder content.
4. Experiment with Ranger for a fresh take once you've mastered the standard builds.
5. This is where armor system mastery separates good players from great ones.

Phase 5 Checklist

• Endgame content on farm
• Best-in-slot gear acquired
• Lady Vengeance fully cleared
• Ready for challenge content

Common Progression Mistakes

• Splitting damage types across the party — having 2 physical and 2 magic characters means neither group can strip armor efficiently. Commit to all-physical or all-magic for optimal CC.
• Ignoring Warfare on magic characters — Warfare scales ALL physical damage, including Necromancer spells. A Necromancer with 10 Warfare deals far more damage than one with 10 Necromancy.
• Not using the free respec mirror — many players feel locked into bad builds. The mirror on your ship has zero cost and unlimited uses. Respec whenever your build feels weak.
• Hoarding Source skills for 'important fights' — Source points refill at fountains and through Source Vampirism. Use your Source skills frequently rather than saving them.
• Selling items without checking the gift/barter interface — giving gifts to merchants increases their Attitude toward you, which directly reduces their prices by up to 40%.
