What do you mean it can Excomunicate? Are mechs in lancer ordained and this is mecha pope?

I don’t think people are ready for the fully unhinged Lancer posts, I know I’m not

From compcon.app, the irl and in universe compendium/builder:

Make a tech attack against a character within Sensors. On a hit, for the rest of the scene, the first time in a round they move adjacent to an allied character during their turn or start their turn adjacent to one, both characters take 3 heat. They can end this effect with a successful Systems save as a full action. This can only affect one character at a time

You basically enforce social distancing.

What’s extra fun is because it’s any character, you can get some funky synergies with friendly mechs that want to have high heat

Also all of the HORUS aligned mechs and ability are all big on mythology (as you can tell from the “faction” name)

Its an ability that punishes an enemy for being near its allies
