I have enchanted a number of blades and shields already, but if anyone requires their specific weapon enchanted, or their garments warded against flame and magic - I will be in the lobby of the complex for a few hours tonight. I will also have those I have already finished there. The other magic-users are welcome to join me, as having it all in one central location may be easiest on everyone.
Everyone who is involved in any way should be armed and protected. Even if you are not taking direct action in the physical fighting, either as an element of distraction, or controlling her fires, I would suggest carrying a small blade, and being defended against her power. You might see an opening others may not have, and it would be wise to be able to take it, if that is the case.
Those in other locations in the city who require transport to avoid her attention, I am still able to take them to the complex, or - as Lois mentioned - to the Winchester home, for safekeeping... though the fewer trips I am able to make, the better - gathering together in the other locations, if there are multiple individuals there, would make matters easier.
