Warhammer 40,000: Dawn of War - Definitive Edition

2.10.0 Update Patch Notes

Relic Entertainment

Today's update marks a full year of support for Warhammer 40,000: Dawn of War – Definitive Edition . Thank you to all the fans, modders, tournament organizers, and balance testers that have kept the community active and engaged – you have given us the opportunity to keep supporting a game that means so much to all of us here at Relic.

Going forward, after any required hot fixes or balance adjustments, the cadence of updates is likely going to slow and scale down as we allow the multiplayer meta to settle and generate more definitive data. Additionally, this will allow our team to spend time on some larger initiatives. The team will still be here, watching for ways to support the community.

As always, please continue to report any issues at https://help.relic.com/hc/en-us to help us prioritize any new or existing issues.

Multiplayer Balance

General

This update looks to improve underused units, heavy weapons, and research, while also fixing some unit inconsistencies and improving some of the worst multiplayer matchups.

Chaos

Chaos are getting a cost increase to Khorne Berzerkers to reduce the effectiveness of some strategies where they were rushed together with the Chaos Sorcerer and could perform well even at a severe economic disadvantage.

Cultists are seeing a buff to their Plasma Guns and a minor buff to Grenade Launchers as well. Defilers are getting back some of their damage against Air units and the Chaos Lord is getting a targeted buff against some factions.

Cultist Squad

Plasma Gun accuracy increased from 40% to 50%, accuracy when moving remains at 30% Grenade Launcher damage increased by 5%

Khorne Berzerkers

Squad cost increased from 200/20 to 220/20 Reinforce cost increased from 50/5 to 55/5

Defiler

Battle Cannon damage against Air units increased by 20%

Chaos Lord

Bolt Pistol damage against infantry high increased by 20%

Dark Eldar

Dark Eldar are getting an increase in the ranged damage reduction of the Energy Field for the Dais of Destruction to help them perform better in late game scenarios. At the same time we are removing Building High from being affected by Corrosion to prevent the Headquarters from being destroyed too easily by Dark Eldar in the later stages of a match.

Wyches are a bit too costly for what they can do after their previous nerfs and are getting a reduction in their reinforcement cost. Raiders are overperforming in the early stages of Tier 2 and are getting a reduction in their health. Finally, the Reaver Jetbike is getting some of its damage against builders back since it was reduced too much in previous patches.

Reaver Jetbike

Ranged damage against Infantry Low increased by 10% on all weapons

Raider

Health decreased from 1600 to 1500

Wych Squad

Reinforcement cost decreased from 60/15 to 55/15

Dais of Destruction

Corrosion

Eldar

The Eldar are getting a targeted buff to the Warlock to help it survive a bit better with the goal of improving the Eldar vs Tau matchup where they are needed to detect and kill Stealth Suits in the early game. Mysticism is getting a slight cost decrease to make it more affordable and further improve Guardians early on.

The Eldar health research are getting a reduction to time cost which will help them come online earlier considering the long research time for all upgrades in the Soul Shrine. We are also fixing the second health upgrade so that it properly changes the armor type of the Banshee Exarch so it matches the armor type change of the rest of the squad.

Guardian Squad

Warlock health increased from 250 to 300

Webway Assembly

Mysticism cost decreased from 125/65 to 125/55

Soul Shrine

Wargear: Reinforced Armor research time decreased from 60s to 45s Wargear: Enhanced Reinforced Armor research time decreased from 60s to 45

Wargear: Enhanced Reinforced Armor

New: Banshee Exarch now changes armor type from Infantry High to Infantry Heavy Medium to match the change in armor type of the normal Banshee squad members.

Imperial Guard

The Imperial Guards have been overperforming and are getting several small adjustments to their strength. Curse of the Machine Spirit is getting a reduction in duration and an increase in cooldown to make it harder to continually stun vehicles in the early stages of Tier 2 and Dauntless Valor is now moved to Tier 3 to reduce the amount of Psykers that can be put in the Command Squad earlier on.

The Guardsmen Plasma Gun, Chimera, and some of the Baneblade weapons are getting small damage reductions to reduce Imperial Guards strength in different stages of the game.

And finally, the Marauder is seeing some improvements to its Heavy Bolters to make them fire more frequently and to deal more damage.

Both Heavy Bolters fire on the move accuracy increased from 5% to 15% Heavy Bolters Horizontal/Vertical traverse speed increased from 45/20 to 90/40 Heavy Bolters damage increased by 20%

Necrons

Necrons are receiving small reductions to ranged damage for the Wraith and Necron Lord after researching Wraith Flight and Phylactery. This aims to improve some matchups where Wraiths were spammed together with a strong Necron Lord and were almost unkillable.

Chronometron is getting its cost reduced to make it more affordable in some matchups where Necrons struggle. Veil of Darkness is also getting its cost reduced since it is the least used out of the Necron Lords artifacts. Solar Pulse has gotten a further increase in its cooldown because of how well it can shut down ranged armies.

The Nightbringer is getting a speed increase to help it better engage and deal damage before it reverts into the Necron Lord again. Both the Necron Lord and the Lord Destroyer are getting increased damage to late game Relic units and the Krootox, which Necrons struggle to counter.

Orks

Orks are having a bit of a hard time in the current meta and are getting some minor buffs to help them out.

Stormboyz are getting back some of the health buff from ‘Eavy Boy Armor that they lost in a previous patch. A couple of Pile of Gunz research are getting lower research time and Even More Dakka will now also increase the damage of the Shoota Squads Big Shootas.

Mega Armored Nobz are still underperforming and are receiving some additional buffs. Their reinforcement cost is being reduced, they now start with a bit more morale, and they build slightly faster.

The Slugga Burnas are too weak and are underused so they are getting a small damage increase in return for some lower damage against lightly armored buildings.

The Space Marine Squad is losing the rebate to the build cost of the squad to reduce the massing of squads early game. Additionally there is a minor reduction to the health that Assault Marines get from the second health upgrade.
