As fans will know, this horrid creature serves as the source of the blight that’s been plaguing Paradise Down. Unfortunately, taking it down doesn’t seem to be as easy as other opponents in the game area so far. After all, its minions and the Harbinger’s innate abilities make them a menace on head-on approaches. However, players can tip the tide in their favor with a few tips.
Updated on June 11, 2025, by Rhenn Taguiam:Unlike other RPGs,Divinity: Original Sin 2offers players a lot of opportunities to tackle their objectives - especially when it involves defeating bosses. With enough Charisma, players may not even have to fight bosses at all. However, in the case of the Harbinger of Doom in Act 2, players may have no choice but to go toe-to-toe against this rather powerful baddie.
Newcomers who fight the Harbinger of Doom on the get-go might see themselves stumped by this boss’s powerful moveset and various immunities. However, with the right strategy and setup, any player can easily dismantle the Harbinger’s defenses and go in for the kill as early as a turn or two.
15Spellcasters Should Keep Their Distance
It’s important to remember that the Harbinger itself has immunities towards Fire, Poison, and Decaying, as well as 20-percent Water Resistance. Moreover, Dead Magisters have 200-percent Resistance (meaning, they can heal) from Poison. On the get-go, these statuses mean players can’t rely on good ol’ burst Spellcasters in this battle.
However, there are certain exceptions. Players can kill the Dead Magisters with Pyrokinetic Skills since they have 50-percent Weakness towards Fire. Players need to note that this won’t work against the Harbinger, though. As such,Spellcasters with a ton of Geomancer Skillsmay be able to take on the Harbinger. However, given their inherent weak Armor and Health, they may still need to be afar.
14Avoid Unnecessary Confrontations
Despite being a miniboss of sorts, the Harbinger of Doom packs a lot of punch in terms of offense and defense. Characters who end up in its path can get wiped in just a few hits. And it doesn’t help that the Harbinger’s minions have quite the annoying set of attacks to whittle the player’s Health. As such, players shouldavoid unnecessary confrontationswith the Harbinger as much as possible.

Rather, players can count on their tanks and stealth to do the job for them. Given the Harbinger’s immunities and resistances, physical attackers such as Knight and Fighter builds and sneaky combatants such as Rogue and Shadowblade builds can take care of the Harbinger safely.
13Run At First Sight
Players need to remember that retreat is always an option for heavy combat against the likes of the Harbinger. If the Harbinger proves too difficult to deal with on the first turn, it may be best to run away from combat for now.
To gauge this, players maywant a character with high mobilityto try and engage the Harbinger. If they can outlast the Harbinger in a turn with health still intact, then perhaps the entire party can engage. However, in the case of the Harbinger pinning the scout in a critical condition, then that scout should retreat as fast as possible to regroup.
12Dispatch Minions First
To avoid the mess of dealing with the Harbinger’s deadly attacks, it helps players to kill its minions first. The Dead Magister Inquisitors and Swordsmen are a mess to deal with in both ranged and melee. And it doesn’t help that the Harbinger aids its minions when they’re in immediate danger.
As such, players might want to use Teleport (Aerotheurge 1) to get some alone time with the Dead Magisters. That, orplayers can set up a vantage pointcloser to the Dead Magisters but away from the Harbinger. That way, they can take care of the Dead Magisters without arousing suspicion.
11Keep Health Plentiful
Players who don’t have the advised Skills to deal with the Harbinger might want to keeptheir recovery Skills and Potions close by for the assist. That way, they can continue to outlast the Harbinger as it zig-zags around the battlefield.

It’s recommended that players enhance their defenses immediately before engaging in combat. Moreover, it may also help to have all characters equipped with one or two recovery Skills such as First Aid (Huntsman 1) and Restoration (Hydrosophist 1) to ensure that they can heal each other and allies nearby whenever necessary.
10Check The Real Estate
Thankfully, players need to traverse a cliff before heading towards the battlefield. In turn, the game already gives them theopportunity to survey the battlefieldprior to combat. In that regard, players should remember that there are four key locations on the map outside the poisonous battleground.
Firstly, the two broken battlements of the castle lie close to the Harbinger. They’re great for ranged incursions that provoke the Harbinger but the Dead Magisters may find difficulty reaching.
Likewise, there are two cliffs that overlook the entire battlefield. The first one lies directly above Almira’s house, from where players can first see the Harbinger. This is a good vantage point to plan ranged attacks. Moreover, opposite this cliff is another cliff that players can reach by teleporting to the ground away from the Harbinger and then climbing.
9Take Note Of Immunities, Resistances
Players should take note of a handy feature called Examine that they can activate regardless of distance. A character with high enough Lorecan obtain a lot of insightfrom enemies. In this particular battle, the Dead Magister Inquisitors and Swordsman have 200-percent Resistance (can heal) from Poison and 50-percent Weakness (extra damage) from Fire. Meanwhile, the Harbinger has 100-percent Resistance (immune) to Fire and Poison, 20-percent Water Resistance, and Immunity from Decaying.
These numbers mean that while the Harbinger and the Dead Magisters are immune from Poison, Magisters can still die from Fire. Meanwhile, despite the Harbinger’s high armor, it’s still vulnerable to physical attacks and non-Fire/Poison damage. Earth Damage, Warfare, and Scoundrel may shine in this regard.
8Take Note Of Harbinger Attacks
Whatever the battleplan players decide on taking, they should try to allocate a Fighter or a Tank Archetypeto take on the Harbinger while they set up more powerful attacks. However, their Tank should be able to take on damage, as the Harbinger’s abilities can become extremely deadly.
For instance, the Harbinger can use Source Vampirism to steal Source from players and then use it against them via Curse. Moreover, its Harbinger’s Wrath and Burning Blaze attacks can easily tear through Physical Armor and Magical Armor, respectively, and even eliminate characters, especially if the Harbinger uses this attack repeatedly.
7Bombs Away With Poison Gas
Interestingly, players who fight the Harbinger focus too much on it and its minions that they forget all the useful things in the environment around them. For instance, the cliff the battle takes place has an abundance of corpses used for sacrifice and Green Noxious Bulbs that secrete poisonous gas.

Players can actually take the time to reposition the Green Nixious Bulbs near the Harbinger’s minions. At first glance, these actually constantly regenerate their health thanks to their poison gas. However, as the game teaches players, poison clouds tend to be extremely flammable. As such, players can use a long-rangedPyrokinetic Skillto detonate the poison cloud. The impact will most likely eliminate multiple minions at once.
6Stay True To Physical Attacks
The Harbinger proves that Scoundrel, Warfare, and Huntsman-based builds still work like a charm againstseemingly strong bosses.Aside from physical attacks working normally against the Harbinger’s Physical Armor, non-Fire/Poison attacks seem to pick off its Magical Armor as well.
However, players who want to play it safe should probably stick to physical attacks. Granted, some elemental attacks affect the Harbinger - but most of them do minimal damage to its Magical Armor. Interestingly, Backstab-empowered attacks from a Scoundrel build can eliminate the Harbinger’s Physical Armor quickly thanks to its auto-Crit. Moreover, these physical attacks can even remove a bit of its HP before the round ends.
