I'm assuming Abel is fully human-level intelligent so Lily's Living Plant Benefit doesn't apply...buuuut given he has a wife I'mma assume her Attractive advantage applies anyway. If I'm wrong reduce the below Persuasion roll by 10 and Deception by 5.
Gonna make a Persuasion check to Improve Reaction to try and persuade him into coming along with us without a fight, hopefully the approach gives enough incentive to make it viable or at least a step in the right direction.
Including a Deception roll as well just in case. Lily's not lying here, but she's making claims that are sufficiently
unbelievable that I could imagine a Deception check might be required regardless of her sincerity. However, since Attractive only applies to attempts to seduce, deceive, and improve reactions, its bonus doesn't apply here (Lily's Scent Intensification bonus does, since it's only Limited to people who are subject to her Attractive advantage regardless of the purpose of the check).
I'm including these rolls in a sub-spoiler so other players can consider whether they want to Team Check without being influenced by the die rolls, also in case that helps with setting DCs.
