These Grim Dawn tips are for players who've finished Normal difficulty and want to push further. If you're still learning the basics, start with our Grim Dawn Beginner's Guide. Everything here assumes you understand masteries, devotion, and gear components.
Damage Conversion Deep Dive
The Conversion Order
Damage conversion in Grim Dawn follows a strict processing order that the game never explains clearly:
- Skill-specific conversion (built into the skill or its modifiers)
- Item-granted conversion (from equipped gear)
- Buff-granted conversion (from toggle skills and auras)
Each conversion step happens once. Damage that was already converted cannot be converted again. This means you can convert Physical to Fire (via gear), but you cannot then convert that Fire to Lightning with a different item. The conversion chain stops after one step.
Practical Conversion Example
The Death Knight's Cadence deals Physical damage. The Krieg set converts 100% of Cadence's Physical to Aether (this is skill-specific conversion because the set modifies Cadence directly). After conversion, you stack +% Aether damage and -% Aether resistance to scale the damage.
If you also wore a belt that converts 50% Physical to Fire, it would do nothing. The skill-specific conversion from Krieg already consumed all the Physical damage in step 1. The belt's conversion (step 2) has nothing left to convert.
Takeaway: Only one conversion source matters per damage type. Find gear that converts 100% of your base damage to your desired type in a single step. Partial conversion (50% Physical to Fire + 50% Physical to Lightning) splits your scaling and makes the build weaker.
Resistance Reduction Stacking
Resistance Reduction (RR) is the single biggest damage multiplier in Grim Dawn, and different types of RR stack differently.
The Three Types
| RR Type | Example | Stacking Rule | |---------|---------|---------------| | Flat reduction (-X%) | Curse of Frailty: -32% | Only strongest applies per type | | % Reduced | Viper constellation: 20% reduced | All sources stack multiplicatively | | Flat minus (-X) | Eldritch Fire proc: -23 | All sources stack additively |
All three types stack with each other. A well-built character stacks all three:
- Curse of Frailty: -32% Vitality resistance (flat reduction)
- Vulnerability (devotion): 20% reduced target resistance (% reduced)
- Rattosh proc: -23 Vitality resistance (flat minus)
Against an enemy with 80% Vitality resistance, the final result: 80% - 32% = 48%, then 48% × 0.80 = 38.4%, then 38.4% - 23 = 15.4%. You've turned an 80% resistant enemy into one with 15.4% resistance. That's roughly 5x more damage than attacking without RR.
The build-making rule: Every end-game build needs at least -100% total RR against its primary damage type. If you can't reach -100%, switch to a damage type where you can. Builds with strong RR kill 3-5x faster than identical builds without it.
Devotion Optimization
The Refund Trick
You can remove Devotion Points from constellations at the Spirit Guide, but only from the last point you placed in that constellation. This creates problems when you want to reorganize your entire path.
The trick: Remove constellation points in reverse order of placement. If Constellation A provides affinity that Constellation B needs, remove B's points first, then A's. The Spirit Guide won't let you remove a constellation that another constellation depends on for affinity.
For major devotion rebuilds, plan the removal order on paper first. It's common to need 20+ individual respec operations to shift from one devotion path to another.
Hidden Devotion Breakpoints
Some devotion proc skills have hidden internal cooldowns or trigger conditions that affect their real-world performance.
Ghoul (healing proc) triggers at 60% health. Many players bind it to their main attack thinking it fires constantly. It actually only activates when you drop below the health threshold, with a 4-second cooldown. This makes it better bound to a movement skill (shadow strike, blitz) that you use reactively when health drops.
Dying God grants +135% All Damage for 12 seconds on a 24-second cooldown. The hidden detail: the buff snapshots your stats when it activates. Activating it while all other buffs are running gives more damage than activating it with buffs down. Sequence your buff activation carefully.
Farming Routes
Shattered Realm 75-76 Strategy
The optimal farming loop:
- Enter Shattered Realm from Conclave of the Three
- Clear Shard 75 (kill all enemies, don't rush to the exit)
- Clear Shard 76 (same approach)
- Open all 3 treasure rooms (the third room costs 10 waystones)
- Exit and repeat
The third treasure room is where the best loot drops. Those 10 waystones feel expensive early on, but the legendary drop rate from Room 3 is roughly 50% higher than Rooms 1 and 2 combined.
Speed tip: Clear trash packs in Shattered Realm by running through them. Most builds can AoE-clear while moving. Stop only for boss encounters. A 7-minute shard clear is good, 5 minutes is excellent, under 4 minutes means your build is properly optimized.
Specific Boss Farming
Certain legendary sets only drop from specific bosses. Notable farming targets:
| Set/Item | Boss | Location | |----------|------|----------| | Krieg Set | Janaxia, Alkamos, Theodin | Steps of Torment, Bastion of Chaos | | Dark One's Set | Moosilauke, Gargabol | Ultimate specific bosses | | Bysmiel's Trinkets | Zantarin | Barrowholm area | | Gargabol's Ring | Gargabol | Ugdenbog |
For set farming, kill the target boss, check drops, exit to main menu, reload, and repeat. Boss respawn is instant on reload. A dedicated farming session (30 minutes) yields 3-5 set piece drops on average.
Hidden Mechanics
Offensive Ability and Critical Hits
OA vs enemy DA determines your critical hit chance. The formula is roughly: Crit Chance = (OA - Enemy DA) / 40. At 3,000 OA against an enemy with 2,200 DA, your crit chance is 20%. Each additional 100 OA adds 2.5% crit chance.
End-game bosses have DA ranging from 2,000 (trash) to 3,200 (super bosses). To maintain a 15%+ crit rate against super bosses, you need 3,800+ OA. This is achievable but requires significant investment in OA-boosting gear and devotion.
Circuit Breakers
"Circuit breaker" skills activate when your health drops below a threshold, preventing one-shots. Key circuit breakers:
| Skill | Mastery | Trigger | Effect | |-------|---------|---------|--------| | Blast Shield | Demolitionist | Below 60% HP | +25% damage absorption for 4s | | Prismatic Rage | Arcanist (Maiven's) | Below 66% HP | +33% all resistance for 3s | | Ghoul | Devotion | Below 60% HP | Massive healing over 4s | | Mark of Torment | Necromancer | Manual cast | 70% absorption for 4s |
Stack multiple circuit breakers for layered defense. A character with Blast Shield + Ghoul + Mark of Torment survives hits that would kill anyone with just one defensive layer.
Monster Infrequent (MI) Items
Green-rarity items from specific monsters (called Monster Infrequents or MIs) can roll with rare affixes that make them better than legendaries. A double-rare MI (rare prefix + rare suffix) with the right affixes is best-in-slot for many builds.
Farm MIs by killing the specific monster that drops them. The drop rate is roughly 20%, with double-rare rolls occurring at about 1 in 200. It's time-consuming but the results can transform a build from good to exceptional.
