The Triarius class in Expeditions: Rome is a melee combatant with a lot of support capabilities. Companions like Syneros, as well as any generic Triarii that you recruit, are the only ones that can equip staves. Similar to pikes, these weapons have attacks that reach enemies that are multiple hexes away. Moreover, these types of weapons can shred the armor of targets. 

This Expeditions: Rome guide outlines the Triarius class skill tree and provides suggestions on the best skills you should focus on for this class. Click the links below to jump to specific skill trees or straight to the best Triarius skills:

The Triarius Class Skill Tree in Expeditions: Rome

The Triarius class in Expeditions: Rome has three skill trees: Medic, Flagbearer, and Destroyer. In each branch, there are tiers requiring you to spend a certain number of points (i.e., 0/1/4/7) before you can obtain new active and passive abilities.

As you progress further in the campaign, you’ll likely have enough to unlock the strongest abilities for a couple of these trees. Still, we’ll cite the best skills for the Triarius class in Expeditions: Rome so that you can prepare for the early-game experience onward.

Note that we’ve outlined which abilities are active (A) and passive (P). Likewise, we’ve added if certain skills have requirements or if they have additional ranks or levels.

Triarius Medic Class Skills

Best Skills for the Triarius Class in Expeditions: Rome

We found that the best skills for the Triarius class in Expeditions: Rome include the following:


Generally speaking, most of the restorative and reviving abilities here are very helpful, especially if you’re playing on higher difficulties. Logistics, though, is one of the better options out there since other classes will want to have more movement points.


War Horn, like Logistics, is another amazing Tier 1 skill, and it’s got a wide AoE, too. Next, you’ve got Inspire and Orator, which are unbelievably crucial if you need allies to continue striking foes and chaining kills. Lastly, Rousing Speech is just icing on the cake due to the massive healing AoE.


As mentioned earlier, one utility function that Triarii have is that staves and pikes shred armor. This is useful if you’re up against bosses or elites (those with laurel leaves on their class icons), as they tend to be heavily bolstered.

The Shredder and Reckless skills, which increase the armor shred value, help in this regard. Unfortunately, this tree doesn’t really provide a lot of bang for your buck compared to Flagbearer.
