[X] Flower of Victory
I don't care about anything else but I would really like to see this option take effect - it's the power most essential to Catherine's character and would probably provoke the greatest thematic resonance from her fight with Hunger. Plus, if Catherine really does go full Shattering Blow, it would be a beautiful inversion of Hunger's position at the beginning of the quest. I'm holding out hope that we may not have to kill Ceathlynn but if she has to die, I think this is the best possible way for her to go out.
I think getting just 2 options would be best, setting the Maiden's threat level to something rivalling or even surpassing the difficulty of all fights beforehand - cementing her status as the Final Boss, without outright dooming us to failure. Equinox Lacing or Unbidden Grace might be good, with the latter being my preference since it opens up the possibility of negotiation and also allows Catherine to be an even more perfect mirror to Hunger, a custom-built Hero with equivalent Arete to our Tyrant.
Regardless, I'm super excited to see the final battle of the quest and very eager to enter the epilogue of AST I!
EDIT: Also,
"There's always an ending," says the Maiden?
Hunger's response can only be one thing, following in the Most High's footsteps:
"Not always."
