The Demoness chuckles at the woman's remarks, her posture slackening, kneeling over the wall on the balcony. "That is close to what I had in mind but not quite." The demoness clasps her hands together, a bit excited that the woman was willing to negotiate. As much as she enjoyed flinging spells about, making a good deal was so much more fun. She was good at it too, no doubt the large bundles of charisma coming from her blood.
"Now, let us make a deal. I will list my terms and what I offer, and you are free to negotiate on such terms. I assume that is fine?" The Demoness offers a toothy grin, her fingers absent mindedly tapping the stone work in feverous delight.
"First, I want you out of this temple. There is something here that is precious that can not exit with you in it. In return, I will find you a place of your suiting, to the point where I will build a spot for your garden, to your exact specifications.
Second, I assume that you hold some amount of power over the plant like beats in these forests. If this is true, I want you to make them stop attacking caravans in our trade routes. At least ones connected to out town, those that aren't I care little about. In return I will assist you in removing the poison from your body that you spoke of. If you do not desire this, then you may make another request instead.
Third, You will serve under my banner from here on forth. In return, I offer to assist in any reasonable goals you may have, to the best of my ability, as long as they don't conflict with my own."
Asheroth pauses for a moment, letting the plant woman think for a moment.
"My terms for the first and second deals are absolute and can't be negotiated. My third term and the rewards you get in return for my terms can be negotiated. Do you have any request, or is what I listed satisfactory?"
(Gonna use a special point for Diplomacy. For obvious reasons.)
