Grim Dawn asks you to make the most important decision on your character sheet twice. At level 2 you choose a first Mastery; at level 10 you add a second, and the pair becomes your class. Crate Entertainment’s official game guide describes the masteries as archetypes you combine “to create your own customized play style,” and that is the right way to read them: neither half is a complete class on its own, and the synergy between the two is the thing you are actually choosing. The stake is that the pair is permanent. Skill points can be refunded later at a Spirit Guide, but in Grim Dawn you cannot change your masteries once they are taken.
What this covers: A decision framework for Grim Dawn’s dual-mastery system — name your playstyle archetype, then pick the two masteries that support it, and know what each pairing gives up. Why it matters: The mastery pair is the one choice a Spirit Guide cannot undo, and the wrong second mastery leaves a hole no amount of gear comfortably fills. Who should pick this: New Grim Dawn players choosing their level-10 second mastery, and returning players planning a fresh character around the current 10-mastery roster.
How the mastery rules box you in
Four rules set the boundary of every decision here.
- Level 2 and level 10. Your first mastery is available at level 2; the second is a level-10 choice. Both the game guide and the wiki state the same thresholds.
- Ten masteries, 45 combinations. The Grim Dawn wiki lists ten masteries, and Crate’s Fangs of Asterkarn page puts the combination count at 45. That figure counts every unordered pair of ten, so nine of those combinations are new with the Berserker mastery.
- 248 skill points, split across two mastery bars. The wiki’s Masteries page totals 248 skill points — 237 from levelling and 11 from quests. Each mastery bar has nine tiers needing 1, 5, 10, 15, 20, 25, 32, 40 and 50 invested points to unlock, and a maximum of 50 points can go into each bar.
- One exclusive skill at a time. Exclusive skills are toggled buffs, and only one can be active. The wiki’s exclusive-skill table gives Soldier, Occultist, Shaman, Arcanist, Inquisitor, Necromancer and Oathkeeper at least one each; the Crate forum’s dual-class guide notes that Demolitionist and Nightblade have none. A pair where both halves want a different exclusive forces a choice.
The practical consequence is that you are not picking two damage sources. You are picking one mastery that supplies your main attack or pet and one that patches the weaknesses the first leaves open — and the patch has to be chosen before you know exactly what gear you will find.
Step one: name your archetype
The fastest way through 45 combinations is to ignore the combinations and answer one question: how do you want to kill things? Crate’s mastery pages describe each mastery in archetype terms, which makes the mapping unusually clean.
| Your archetype | Lead masteries | Pairings to consider | What the pairing gives up |
|---|---|---|---|
| Melee bruiser | Soldier, Nightblade, Shaman, Oathkeeper | Blademaster, Warlord, Warder, Dervish | Reach and caster tools; points go into weapon damage and defence instead of cast speed |
| Caster nuker | Arcanist, Occultist, Demolitionist, Necromancer | Sorcerer, Warlock, Spellbinder, Mage Hunter | Durability — the second mastery has to become your defensive half |
| Ranged | Inquisitor, Demolitionist | Purifier, Vindicator, Tactician, Infiltrator | Any skill locked to melee or two-handed weapons |
| Summoner | Necromancer, Occultist, Shaman | Cabalist, Ritualist, Conjurer | Your own damage; pet-scaling pets ignore your personal stats |
| Retaliation | Oathkeeper, Soldier | Warlord, Sentinel, Archon, Paladin | Killing power at range, until retaliation added to attack covers it |
Read the table as a starting direction, not a tier list. None of these pairs is the only answer for its archetype.
Melee bruiser
The Soldier is the natural first half. Crate’s Soldier page says the mastery has “the highest health and physique of all Masteries,” and it frames the soldier as a close-range fighter whose blows “leave enemies bleeding out.” Add the Nightblade and you get the Blademaster: a physical and piercing dual-wielder with the Soldier’s frame underneath it. The wiki’s Nightblade description is the honest caveat — nightblades “are not suited to go toe to toe with tougher enemies,” which is exactly the hole the Soldier fills.
Alternatives are the Warlord (Soldier plus Oathkeeper, a shield-and-physical build), the Warder (Soldier plus Shaman, aimed at two-handed Savagery and Primal Strike) and the Dervish (Nightblade plus Oathkeeper, dual-wield with a retaliatory edge). The cost of every one of them is the same: you are spending your 248 skill points on weapon damage, offence and armour, so the cooldown-reduction and energy tools that make casters flexible are thin or absent. For how those points land once the pair is chosen, the site’s Grim Dawn masteries and devotion guide walks through the affinity pathing.
Caster nuker
The Arcanist is the clearest caster lead: the guide describes it as warping “the mysterious Aether and the elements,” and closes the description with the trade-off — “such tactics leave little room for defense.” Its Reckless Power section calls the playstyle a “glass cannon” outright. That sentence is the whole reason a caster usually wants a defensive second mastery rather than a second nuke.
The standard pairs are the Sorcerer (Arcanist plus Demolitionist, elemental and fire), the Warlock (Arcanist plus Occultist, chaos and aether with curses), the Spellbinder (Arcanist plus Necromancer, aether and vitality) and the Mage Hunter (Arcanist plus Inquisitor, elemental with runes and a heal). Occultist and Necromancer can also lead on their own — the Occultist guide lists “abhorrent curses” and forbidden summoning, while the Necromancer guide leans on sapping vitality and conjuring skeletal minions.
Watch the exclusive-skill clash. The Crate forum guide gives the example directly: an Arcanist who wants Star Pact’s cooldown reduction will lose it if the second mastery is Inquisitor, because Aura of Censure is also exclusive and only one can run. Pick the second mastery’s exclusive before you fall in love with the first one’s.
Ranged
Two masteries own this archetype. Crate describes the Inquisitor as one that “excels with ranged weapons, even opting to wield two pistols at the same time,” supported by elemental runes and Word of Renewal as a heal. The Demolitionist “prefers to fight at range, engaging enemies with guns, traps and thrown explosives,” with a fire-and-electricity arsenal the guide sums up as being for pyromaniacs.
Put them together and you get the Purifier, the archetypal gun build. Inquisitor also pairs usefully as the support half of the Vindicator (Shaman plus Inquisitor, two-handed lightning or ranged), the Tactician (Soldier plus Inquisitor) and the Infiltrator (Nightblade plus Inquisitor). The community’s dual-class guide calls the Inquisitor “a great secondary class, especially for elemental builds or ranged,” which matches what its skill list offers.
The cost is weapon-locked skills. The wiki’s weapon-pool tables show the pattern: the Shaman’s Feral Hunger and Upheaval “require a two-handed melee or two-handed ranged weapon,” the Soldier’s Forcewave needs a shield or two-handed melee, and the Nightblade’s Dual Blades techniques are listed for melee dual-wield. A ranged build can spend points into masteries whose signature skills it will never fire.
Summoner
Three masteries summon, and they summon different things. The Necromancer raises skeletal minions and has “Reap Spirit” and a Blight Fiend; the Occultist calls “a fiery Hellhound or a loyal Storm Raven”; the Shaman summons a Briarthorn and a Primal Spirit. The wiki’s summons tables list those pets per mastery, and the official combat page draws the line that matters for planning: pets are either pet-scaling — which “scale separately from you and benefit from special bonuses … which only apply to these pets” — or player-scaling, like Thermite Mines and Totems, which gain your stats.
The three summoner pairs are the Cabalist (Necromancer plus Occultist), the Ritualist (Necromancer plus Shaman) and the Conjurer (Occultist plus Shaman). What you give up is direct damage: if you are not casting a nuke, your contribution is buffs and curses, and a pet-scaling army only performs if you find gear with pet-only bonuses. The upside is that the summoner does not need the defensive layering a caster does, because the pets stand between you and the damage. If the abbreviations around pet bonuses and effective health start blurring, the site’s ARPG glossary covers the terms.
Retaliation
Retaliation is the archetype that changed most, because for years it only worked when enemies hit you. Crate’s combat page documents the fix: with the Forgotten Gods expansion, some skills gained Retaliation Added to Attack, which adds a portion of your retaliation damage to the active skill. The guide notes it is “scaled by your % Retaliation Damage bonuses and does not scale further with regular % Damage bonuses,” so a retaliation build invests in retaliation percentages rather than ordinary damage percentages.
The Oathkeeper owns the theme — its guide promises that “every blow they receive is returned a thousand-fold” — and the wiki’s skill tables show Aegis of Menhir carrying retaliation-added-to-attack effects. The Soldier is the other half: its skill list includes Counter Strike, whose retaliation-added-to-attack share climbs with investment. That makes the Warlord the default, with the Sentinel (Occultist plus Oathkeeper), Archon (Shaman plus Oathkeeper) and Paladin (Inquisitor plus Oathkeeper) as the variants.
The trade-off is that retaliation is passive by nature. You are tanking hits to deal damage, so your kill speed against enemies who keep their distance depends entirely on how much retaliation your active skills carry.
What the Berserker added
Fangs of Asterkarn is out — Steam and GOG both list a 23 July 2026 release date — and it adds the tenth mastery. The Berserker is a dual-wielding shapeshifter that can take a werewolf form or a wereraven form, working in cold, bleeding and piercing damage. It is also the mastery the current expansion requires: Crate’s Fangs of Asterkarn page states the expansion needs the base game plus the Ashes of Malmouth and Forgotten Gods expansions.
Its signature mechanic is Onslaught. The combat page describes stacks built by an Onslaught ability that are then consumed by any cooldown ability, with “each stack of Onslaught increas[ing] the cooldown skill’s damage by 15%.” That is a melee-leaning, cooldown-weaving archetype rather than a pet, caster or ranged one, which means a Berserker pairing is mostly a decision about which of the nine existing masteries covers its weaknesses. Since 45 combinations exist, nine of them involve Berserker — and with the expansion only months old, pairing advice for those nine is still being written by the community.
The short version
Name your archetype, then pick the one mastery that delivers its damage and the one that patches what that mastery cannot do. Check the exclusive skills before committing, because a pair that wants two different exclusives has already given one up. Remember that some skills are locked to a weapon type, so a pairing whose best skill needs a two-handed melee weapon will not fire on a dual-wield build. Then spend the points and let a Spirit Guide fix anything except the masteries themselves.
