Don't know if you discovered it, but this is how I grind for raptures, provided you are a high enough level:
Before going on a mission, in the party screen:
- Set Viviene to Martyr stance
- Set her Martyr Support Skill to Martyr's Call
- Set hero to Guard stance
- TAKE NO OTHER COMPANION, but if you do, make sure to set them up with a stance that is more support than damage oriented
Then:
Go for a Ruin Investigation mission
Get an encounter with a lone goblin, if you have to kill other enemies, then do so, BUT DON'T KILL THE GOBLIN, we need him alive so that the battle doesn't end (duh), and since he is the weakest possible enemy in the ruins he won't accidentally kill Vivienne
The grind:
Spam Martyr's call - it gives rapture progress on use and gives a +80% boost to further rapture progress gain. It also stacks with itself, so if you spam it long enough, after a while you will gain one rapture level per Martyr's call use.
Spam Hero's Guard Support on Vivienne, mostly as a way of skipping his turn, but also to make sure she survives, after all Martyr's call also aggro's enemies to her.
Continue the process until you get enough Raptures to get her to upgrade. Then do it again to get her to upgrade again, and again, and after you get her to the final stage, realize one of two things:
- Upgrading Vivienne is a pain, and it's hard to say if it is meant to be a pain
- You still can't give her any weapons, unlike anyone else.
P.S. to CM: I don't hate upgrading Viv, but she is easily the most grindy of them all. Even Fern takes less time to reach Elder Stage. Viv really needs a rebalance imho.
