Excellent. She relays that when it glows it's working, and that if it stops glowing it needs to be returned to be refreshed, or it's finished its work.
And then she... doesn't know what else to do with herself, frankly. Mostly what she wants right now is for all of the people currently sheltering inside her walls to get lost and let her have some space. It has been a subjective eternity that she's been beholden to giving a shit about other people's opinions at all times. Considering the situation, that's not really actionable, though. The local dungeon is in fact still the safest place for them all to be, even if the local dungeon kind of wants to mope about killing people. A cold and mercenary part of her is tempted to demand that if they stay inside, they should do something productive, which will either get them to directly help her or get out, but, well. She's still on dungeon probation, and has an enormous amount of power over all of these people. It'd be messed up to put them in such a position. She will not take out her recently blackened mood on people she wants to help and protect, even if she's still really very cranky about wanting to be left alone for a little while.
Hm, well. She won't demand or leverage anything of them in particular, but she's not against positive incentives. There are some coin-shaped materials that are good for enchanting and haven't been enchanted. It won't compare to something properly built for shielding - if nothing else she wants to reverse engineer the loot from the various people she horrifically slaughtered - but a shitty shielding enchantment is better than literally nothing. She leans on crafting with concepts for this, because these are meant to be basic bitch shitty enchantments that go under other, more specialized things. So: if something is moving (this) quickly or faster towards the body of the holder, it'll instead be directed off course, within this set distance around the holder. It won't do anything against temperature, poison, strangulation, or a really slow sharp object, but again: better than nothing. This takes a bit of finesse, but she has it carefully wrapped up around one eiko. From there, she sets the diamond inside to give off a faint (blue, obviously) glow if the associated coin it's attached to is still functioning properly. There will be no surprise failures on her watch, thank you, she knows what failing gracefully is.
This sorted, she enchants all of the available eikos she has, and informs everyone inside the dungeon. "I've figured out a basic shielding enchantment that I'm going to put on every eiko I give out from now on. If anyone got any before I did this, and hasn't exchanged them for something, just shuffle the coins where I can get to them and I'll fix that. The glow is to denote that the shield is functioning; if it stops glowing, please bring it back to me for free renewal."
Does she still sound a little bit detached and mechanical while saying this? Yes. Yes she does. With a touch of emotionally exhausted, which she definitely is. Okay, people, give her the dungeon nom noms if you're going to be here, disturbing her precious introvert time.
