Not every character in Warhammer 40K: Tacticus is useful. Some have absolutely no use and aren’t even necessary for their respective campaign. Others are useful across the board and should be focused on heavily. Without knowing which character belongs in which category, you might be wasting materials and upgrades on potentially worthless characters.
That said, it’s not exactly a waste since you can try and run whatever team comp you want in Arena or Guild Raids, but you can severely hinder your progress and hamstring yourself later on down the line by misallocating resources. If you’re trying to plan ahead and figure out which characters are best for each campaign, here’s a quick rundown of who to focus on.
Indomitus and Indomitus Elite
Main: Bellator, Certus, Varro
Side: Yarrick, Isabella, Calgar, Vindicta, Celestine
The very first campaign, unfortunately, requires you to upgrade two characters that are essentially useless outside of the campaign. Bellator is a great pick for Arena, Guild Raids, and these two campaigns, but Certus and Varro are pretty much useless. Varro has some use in Arena but is easily outclassed by other characters.
Unfortunately, you’ll be forced to use Certus and Varro. For Indomitus, you can probably get away with keeping them low Bronze, but Elite will require them to be higher, perhaps Silver 2 or 3. Luckily, you can use Isabella to try and keep them alive while your higher-level Bellator and Yarrick or Calgar clean up the rest of the enemies.
Indomitus Mirror and Indomitus Mirror Elite
Main: Aleph-Null, Makhotep, Imospekh
Side: Anuphet, Thutmose
There are only five options for these two campaigns: the Necrons. You should try and focus on leveling Aleph-Null and Makhotep, as they’re two of the best Necrons, with Aleph-Null being a great pick in Arena and against certain Guild Raid Bosses. Anuphet and Thutmose aren’t as useful, but leveling them can be beneficial for completing the campaigns with all three medals and for certain Legendary Release Events.
Fall of Cadia and Fall of Cadia Elite
Main: Angrax, Archimatos, Haarken Worldclaimer
Side: Nauseous Rotbone, Maladus, Typhus
Angrax, Archimatos, and Haarken Worldclaimer are required for levels in Fall of Cadia, so it makes sense to upgrade them to at least Silver 3 if you plan on finishing Fall of Cadia Elite. That said, Haarken isn’t exactly useful outside of FoC, so try to avoid investing too much into him. Angrax and Archimatos are great in other modes, specifically LREs for Angrax and Arena/Guild Raids for Archi.
Other characters you can bring along for the ride include Rotbone for healing and sustainability, Maladus for damage, and Typhus for huge amounts of AoE and a psychic tank. The Thousand Sons can also be useful, specifically Yazgahor and Thoth.
Fall of Cadia Mirror and Fall of Cadia Mirror Elite
Main: Thaddeus Noble, Kut Skoden, Sibyll Devine
Side: Bellator, Yarrick, Isabella, Calgar
Fall of Cadia Mirror and its Elite Campaign are pretty flexible when it comes to choices, but it does have three main characters that you will have to focus on for some levels. Thaddeus Noble, Kut Skoden, and Sibyll Devine are required for most levels, forcing you to level these characters up.
Luckily, Thaddeus is useful in multiple aspects of the game, and Kut and Sibyll are often used in Legendary Release Events, making them all decent choices to level. Focus more on Thaddeus, though, as his damage in Guild Raids and passive ability make him a great choice.
For the last two slots or on levels that let you pick whoever you want, Bellator, Yarrick, Isabella, and Calgar are all great choices, but you can’t really go wrong with any of the other Imperial characters that are useful in Guild Raids or Arena such as Celestine or Castellan Creed.
Octarius and Octarius Elite
Main: Gibbascrapz, Snappawrecka, Snotflogga
Side: Boss Gulgortz and Tanksmasha
Like Indomitus Mirror, you can only use one faction for Octarius and Octarius Elite. The Orks have a horrible reputation among Tacticus players, but they can be decent if you invest in them. Certain Orks are more useful than others, such as Gibbascrapz, Snappawrecka, and Snotflogga.
Unfortunately, Boss Gulgortz and Tanksmasha are pretty useless and easily outclassed by other characters in the game. Therefore, you should try upgrading Gibba, Snappa, and Snotflogga. Snotflogga’s active can easily fill the field with summons but be careful as they can easily die and force Gibba’s tank to flee.
Main: Brother Burchard, Sword Brother Godswyl, Ancient Thoread
Side: Yarrick, Bellator, Isabella, Celestine, Calgar
Octarius Mirror doesn’t have an Elite Campaign yet, but should get one soon. Regardless, the same characters will be useful for both. We suggest focusing on upgrading Brother Burchard and leaving Sword Brother Godswyl and Ancient Thoread as low as possible.
Godswyl sees some use in Legendary Release Events, so you can level him as needed, but Ancient Thoread is widely regarded as one of the worst characters in the game. You might have to take him to S1 or S2 to complete the eventual Elite Campaign, but you should be able to keep them both at around Iron 1 or Iron 2 and 3-Medal the Mirror Campaign.
For side characters, you can pick just about whatever Imperial characters you want. We suggest sticking with the characters you’ve been upgrading for Indomitus and Fall of Cadia Mirror to avoid spreading your resources too thin.
Main: Calandis, Aethana, Eldryon, Maugan Ra
Side: Jain Zar
Like Indomitus Mirror and Octarius, you can only use Aeldari characters for the Saim-Hann Campaign. Luckily, just about every Aeldari character is useful in different parts of the game. You’ll need to upgrade Calandis, Aethana, and Eldryon, as they’re the main three, but Maugan Ra and Jain Zar are useful too.
Jain Zar isn’t too great outside of the campaign, so you might want to stick to upgrading the other four. The other four should be enough to carry you through the eventual Elite Campaign, especially Maugan Ra and Eldryon, as they’re extremely useful in Guild Raids and should be highly leveled anyway. Aethana is useful as well in Guild Raids, depending on your team comp, while Calandis is a beast in Tournament Arena, making them both great choices, too.
