Meesei looked over the bottle. From what Sabine had told her in the past, the ingredients for spell reflection potions were indeed rare and expensive, so it was unlikely they would be able to obtain more than the single potion. "Would there be any negative effects on the user's ability to cast magic? If not, I can carry it. With an illusion spell, I may be able to trick the hagravens into believing it is safe to use their magic against me. However, whoever uses it will need to go up alone, while the others guard the lower floor." Meesei took another look at the map to match its layout with her memory. "We will also need do designate a meeting point away from the keep in the event we get separated in our escape. I suspect we will be able to do that easily enough on our way there, but there is another thing that is concerning me. Ariel, Ahnasha, you two are going to need to go after three different targets, and for two of them, it does not seem there is a way to eliminate them without drawing the attention of the coven. As soon as the contents of one of those towers is ignited, at least some of the witches are going to try and find you. I wonder, is there a way you could set one tower to ignite without you being present? Fire runes are effective, but you have to directly contact them, or hit them with a spell, to detonate them." Meesei sighed and thought for a few moments before an idea popped into her head. "Sabine, I recall you once made an explosive alchemical concoction using fire salts and some other ingredients. I know we did not have any fire salts before coming here, but were there any in the hunters' supplies. Or is there somewhere else we can obtain them? I have an idea."
