- Manually controlled necromancy - 1x1 tile AoE workshop, resurrects undeads around it.
How about, instead of a 1x1 workshop, creating an immobile monolith-like creature that animates the dead in a radius around it? It could be created in a workshop and hauled around as needed. Most importantly, invaders can also destroy it without having BUILDINGDESTROYER.
Thats another option, yes. Maybe I can add both. I do like the idea of a "necromantic circle", and a Warlock does a ritual to raise all the corpses nearby, but an automated AoE creature is easier for people that want to raise all the corpses. Just need a good concept for it. What kind of creature would you make it?
Some "Zombie Master", or a "Dark Crystal" type?...
Hrm. Well I'm a big fan of "making pacts with strange and eldritch beings for power"...
Maybe a large featureless blob trailing several tendrils? I'm note sure if you could cover it in a thousand, unblinking eyes or have them constantly whispering secrets in utterly unpronounceable languages, but I'm not good at this "modding" thing. For bonus points, make it be composed of a
really soft metal and bleed dust/ash.
Lore-wise, it should probably be a servant of another entity that the Warlocks worship, gifted to them for their service. Might they be summoned through a sacrificial altar?
If you want to prevent their weaponization (since endlessly reanimating corpses during battle tends to lead to short battles) you could make them highly killable. As in, have them bleed out fairly rapidly.
