"I can also provide money. Even if we are limited to what I currently have direct access to thats a decent amount, and if we're actually staging an army from my world we'd be able to draw directly on virtually unlimited government funding.
The other downsides sound more serious. We have non-sentient drones that might be useful, but they lag behind what really powerful people can do and I'd worry about hacking.
Wards protect against a laundry list of things specific to that ward. Basically all of them block physical entry/exit by people, and direct targeting of magical effects across their boundary. Other things are added as one offs with an upper limit of 9-12 total 'bans' depending on the exact ban combo. What counts as a 'specific banable thing' is complicated and not something I fully understand.
But some general rules are that it has to involve crossing the boundary of the ward, it has to be symmetrical, and that you can't put in exceptions just do more complex ban sets.
To give an example of each of those; you can't ban starting fires even though you can ward against fire spreading, you can't forbid entry without forbidding exit, and you can't ban all people except specific species even though you can forbid humans and Mlargos as two separate bans.
You generally can't stack wards though my specie's sleep pods are an exception. They can hold two wards dirrectly and are compatible with being inside a warded building. It's also normally sacrilegious to even imply that its possible to loan then out, but we have explicit exceptions for just this sort of emergency."
In practice it would still mean the death of whoever no longer had a proper sleep pod, but ey can bring that up after Griffie decides if there is a tactical application.
Wait Griffie gets all whiny about that sort of thing.
"Also, whoever loaned it out would have to enter time stasis while it's in use then commit suicide afterwards. Because we are spawned with a single pod that stops working on our deaths and allowing an alien inside one renders it permanently ritually impure. Unless the owner is inside at the same time but that seems impractical for someone your size."
"And to address the obvious follow up time stasis requires a whole facility with relatively tiny pods inside it, we don't have bobblers outside of fiction or I'd have lead with that."
