War Museum Offensive 101 - Revised for 2026

[Abhorsen]

Hello everyone - This is a revised 2026 Museum for attacker 101

Most players usually start their journey as an attacker as they progress to Robotic Age these days:

Offensive players want to place priority on 3 stats from equipment:

1) All Enemy Defensive Tower Damage (AEDTD) - Negative value
2) All Enemy Defensive Tower Health Points (AEDTHP) - Negative value
3) Enemy Defender Spawn Time (EDST) - Positive value

It should be noted that there is a cap for stats that are negative integers of -85%. Any negative value above -85% will be wasted and not calculated into the war battle. The calculation is set up and determined via the domination server and is completed at the start of the match.

Warning - You can't do -85% AEDTD and -85% enemy single tower defense lines (I.E. Redoubt, Tower, Air Defense, and etc.). The AEDTD and AEDTHP will always be calculated first before it looks at a single tower line for negative integers. It's just how it is coded in the game. It should be noted that the Road Map of 2026 - Developers are wanting to look into removing the -85% cap for negative sometime in the future. This guide will have to be revised in the future. If they succeed in this major change to the game.

Priorities have changed a lot now as fighter and bomber museum builds are completed for rebalances.

Fighters - Rebalance 2025. They can no longer destroy bases with high gun damage on buildings anymore. The strategy used to follow tactics of demo on air defense buildings and proceeding to finish them off with recon and sniping them. They normally would pick off all the other towers easily afterward unless S.A.M. or GDI traps got them. Troops would clean up the remainder of the bases. Fighters now can only do heavy damage to defender troops - Main Battle Tanks and Heavy Tanks only after the rebalance. The meta is dead for high end alliances.

Bombers - Rebalance 2026. Most people used specialized building (I.E. Night Hawk Hangar and Fortified Stronghold to provide 2 slots to Airstrip and 1 extra TT slot for Stronghold - 1 extra bomber for the airstrip and Tupolev / Recon for TT stronghold.

The strategy had a wide variety in choices from people using Tactical Helicopters and Commandos to pick off the Air Defense buildings and destroying the remainder of the base with no contest as Tupolev would normally go in next for the first wave to eat all the air traps. The 5 bombers from the player airstrip would clean out the rest of the base with the help of recons.

A bunch of changes happened to the bombers - Slower movement speed, and less bombs per run. In exchange they gained faster attack speed. This meta isn't completely dead, but not the best for any war that requires speed runs to win in a war.

Lego Meta - About to experience a change to the meta in March due to the rebalance of coalitions - We're still waiting on the news from developers - We do know so far that Mongol has been shifted to providing attack speed and extra troop damage to detachment C troops. You must have troops assigned to troop C to gain this buff. That's all we know so far. More to come in March for now. It follows a mix of normally Mortar, Range Siege (Artillery), and APC units to function well. Mongol buff is what makes this shine so much right now with 76% attack speed bonus. This meta is the best right now for war - Speed Runs and Non-Speed Wars. Most D bases just don't stand a chance against these attackers depending on the attacker skill level.

It should be noted that all museum gear can possess 5 lines of the same unit dmg or health. Same for AEDTD, AEDTHP, and EDST. You may only select one line on each equipment to reroll for 100 crowns. Pick the line that has no synergy for your troop formation for rerolling. Try to shoot for gear that has 4 lines for your troops.

For me as a Lego player: I tend to look for weapons like this now:

Weapon: Damage %
1) Mortar / Paratrooper (PT) / RS 6%
2) Mortar / PT / RS 6%
3) Mortar / PT / RS 3%
4) Mortar / PT / RS 3%
5) Mortar / PT / RS 1%

Armor: Health %

1) Mortar / Paratrooper (PT) / Heavy Infantry (HI) (APC user) / RS 6%
2) Mortar / PT / HI / RS 6%
3) Mortar / PT / HI / RS 3%
4) Mortar / PT / HI / RS 3%
5) Mortar / PT / HI / RS 1%

Equipment is hard to say as we have showcase introduced now too. You can get near > -40% AEDTD from just showcase. 4 slots for Equipment - Hear me out this is going to get crazy.

Step 1: Showcase your AEDTD first and get the % from that first.

Equipment 1
1) AEDTD -6%
2) AEDTD -6%
3) AEDTD -3% Until -85% is reached with the showcase values too.
4) AEDTHP / EDST -6%
5) AEDTHP / EDST -6%

Equipment 2
1) AEDTHP -6%
2) AEDTHP -6%
3) AEDTHP -3%
4) AEDTHP -3%
5) AEDTHP -1% -85% is reached. There are no showcase values for AEDTHP yet.

Equipment 3
1) EDST 6%
2) EDST 6%
3) EDST 3%
4) EDST 3%
5) EDST 1%

Equipment 4

1) EDST 6%
2) EDST 6%
3) EDST 3%
4) EDST 3%
5) EDST 1%

Hermitage slot (Wonder)

1) EDST 6%
2) EDST 6%
3) EDST 3%
4) EDST 3%
5) EDST 1%

Hermitage - EDST now has higher value than a weapon in my opinion for battles. The less defenders the better. You won't need high damage when you're not needing to kill so many troops quickly. Weapon is fine too. Pick your poison.

*Bombers - This is mainly the same logic, but for weapon you want bomber damage and armor is bomber health. The equipment is mainly the same. EDST doesn't matter to you. Defenders can't attack your bombers. But it will help your troops for clearing or commandos for picking off D buildings with no defenders chasing them. Hermitage should still focus on armor to be in your slot. More bomber health the better you'll be off in the long run.

Hermitage slot (Wonder) - Armor

1) Bomber HP 6%
2) Bomber HP 6%
3) Bomber HP 3%
4) Bomber HP 3%
5) Bomber HP 1%

Each gear can give you a line % of 1%, 3%, or 6%. Try to get 2 lines of 6%, 2 lines of 3%, and 1 line of 1% for same troops. Ideally try to get 4 of the same line and reroll the 5th line.

Hopefully this helps out some new players that are wanting to explore more about Museum and how to be efficient in looking for new gear as an attacker.

Thank you.

For the -85% debuff cap...is this a net cap?

For example:

If I have All Enemy Defender Tower Damage of -100%, and the enemy is at +50%, what is the debuff? Is it -50%, or is it -35%?

Good evening,

I wanted to make an helpful guide to starting the path of building a war museum for your base. There are 3 types of museums you can design: Pure Offensive, Pure, Defensive, or Hybrid model that has a mix of both characteristics. - Hopefully I will get into Defensive and Hybrid builds in a later date.

Most players usually start their journey as an attacker and progress to defensive gear as each war crafting event occurs in game.

Each museum has 2 weapon, 2 armor, 4 equipment, 3 legendary, and 1 wonder slot.

Offensive players want to place priority on 3 stats from equipment:

1) All Enemy Defensive Tower Damage (AEDTD) - Negative value
2) All Enemy Defensive Tower Health Points (AEDTHP) - Negative value
3) Enemy Defender Spawn Time (EDST) - Positive value

It should be noted that there is a cap for stats that are negative integers of -85%. Any negative value above -85% will be wasted and not calculated into the battle.

This theory is true for - Enemy Tower, Air Defense, and etc. You don't want these stats if you're cap on AEDTD and AEDTHP - They will be wasted.

Warning - You can't do -85% AEDTD and -85% Enemy Tower Dmg. The AEDTD will out rank the Enemy Tower Dmg. You should also watch out for this in your council members too. But that's a whole different topic for another time.

Some players go really high in stats for EDST, but most people need values that break 160 to 180% criteria to see any defensive bases affect by slower defender spawn time. Most people that go that route need to use Hermitage wonder slot for equipment to gain an extra 30% EDST.

Many players go the other route and craft for higher maximum damage or health to units (Bombers / Fighter) layout.

I.E. - a Mortar, RS, and APC specialist- Lego player will normally value a third weapon in their Hermitage slot.
I.E. - a Bomber or Fighter specialist - Will tend to put an armor piece in their Hermitage slot to increase the health of their planes.

It should be noted that all museum gear can only have 2 lines of the same unit dmg or health. Same for AEDTD, AEDTHP, and EDST. You may only select one line on each equipment to reroll for 100 crowns. So pick the line that has no synergy for your troop formation:

For me as a Lego player: I tend to look for weapons like this: Below is my opinion only. Some players may value their paratroopers more than Generals.

Weapon:
1) Mortar dmg
2) Mortar dmg
3) RS dmg
4) RS dmg
5) Paratrooper dmg

Armor:
1) Mortar Health
2) Mortar Health
3) General Health
4) General Health or Paratrooper
5) Paratrooper Health

Equipment
1) EDST
2) EDST
3) AEDTD - Until -85% is reached
4) AEDTD or AEDTHP
5) AEDTHP - Until -85% is reached

Each gear can give you a line % of 1%, 3%, or 6%. Try and get 6% lines.

Hopefully this helps out some new players that are wanting to explore more about Museum and how to be efficient in looking for new gear as an attacker.

Very helpful. Great post

Very helpful. Great post

Mmm, l wonder if this needs a tweak now that we have the showcase?

Waiting on 13.4 coalition changes first as there a lot to change after that.

Thank you.

For example:

If I have All Enemy Defender Tower Damage of -100%, and the enemy is at +50%, what is the debuff? Is it -50%, or is it -35%?

At this point of time the game is cap at -85% for AEDTD and AEDTHP. They’re looking to reevaluate this in the future for 2026. No clue how yet.

But the server calculate the opponent bases against each other and is always at -85% for the attacker. If you have -100% it will just recognize the -85% and calculate that only. It’s like the -15% was never there.

If the enemy has 50% ADTHP or ADTD then yes it is going to have it calculated as you’re at -35%

gran trabajo. ¿Puedo pasarlo por mi canal de youtube? me parece muy útil para que los nuevos vengan a leerlo en el FORO del juego .

Great work. Can I share it on my YouTube channel? I think it would be very useful for newcomers to read it on the game's forum.

I’m fine with it. Please feel free to share it on your YT.

the guide is outdated.
i.e.

It should be noted that all museum gear can only have 2 lines of the same unit dmg or health. Same for AEDTD, AEDTHP, and EDST.

now we can have 5 same unit lines in one artifact. (max 2 lines per %-value) e.g.
Weapon:
1) Mortar dmg +6%
2) Mortar dmg +6%
3) Mortar dmg +3%
4) Mortar dmg +3%
5) Mortar dmg +1%

Yeah - I was planning to update it after 13.4 coalition update to see what’s going to happen to war battles.

This has been revised for now.

 

[Krauserthesecond]

1) Mortar dmg +6%
2) Mortar dmg +6%
3) Mortar dmg +3%
4) Mortar dmg +3%
5) Mortar dmg +1%

Did anybody ever manage to get something like this?

It’s possible. I have 2 that is 4 liners. I haven’t reach 5 liner yet. Here - examples:
