Nothing that you wouldn't be able to operate without a little explanation.
They're all objects that are meant to even the odds in a fight against a demon. Sure, we've got our holy water and our Devil's traps, but in a fight against something stronger and faster than you, you're going to need to be able to turn everything over on them in unexpected ways or they'll have you down before you can so much as blink at them.
I've taken what we know and I've enhanced on that. Holy water infused sprinkler systems that go off when exposed to a distinctive signature of sulfur, devices that take all of ten seconds to laser imprint a Devil's trap on the floor.
And that's just the bare minimum on the most basic elements of security. We haven't even touched defenses yet.
Come to the lab. Take a look. If you find it all appealing, you can stay and help. If not, then we'll find something else for you.
