As for the future, -1 to attempting to recruit Proxxy. My reasons for this:
- It probably won't work. The only reason we were able to recruit Riltia at the beginning was due to her having no clue that she is a Sibling and therefore should be working for Oric and trying to kill Ciro. It's possible she still has no clue.
- Proxxy is powerful. If we want to have a snowball's chance of killing her, we will need to strike quickly. We need to get an attack in first. Attempting diplomacy will just open up ourselves to an attack.
- We are supposed to kill Proxxy. If we want to advance in the story, we'll need to do what we're meant to do: kill Siblings. Proxxy is hostile towards us, and will try to kill us. We need to kill her first. In the words of Captain Malcolm Reynolds, "If someone tries to kill you, you kill them right back."
As an implication of #3, like I stated earlier, we will need to kill Riltia at some point, too. Not yet, because she's useful and friendly. But if she stops being either one of those, we should consider actually doing what the angel statues told us.
1. I'm uncertain. We have an excellent reference, and Proxxy strikes me as a reasonable--almost neutral--Sibling.
2. I'm not convinced this is a factor. Especially since pretty much every enemy has given us at least one free Diplomacy attempt.
3. We were supposed to kill Riltia, remember? It was a specifically-given Quest.
- If we fail to recruit her, she will get the first attack. The risk is too much. And what makes you think we'll be fighting just her? It's more likely she'll have a Searchbot or two with her.
Your other questionable arguments aside, if one round is so great a risk we can't try a different strategy than "shoot it and hope the dice love us" then we shouldn't be in the fight in the first place, because that's not how this game works.
Agreed.
Especially since recruiting Proxxy would take a much shorter order of "The dice love us"...
May leaving Proxxy at low HP increase the chances of "persuading" her then?
I'd prefer saving "shotgun diplomacy" for a last resort, and to follow it up by earning Proxxy's trust. To do otherwise is inviting vengeance...
Oh, and -1 to "Tactical Persuasion". Aside from that just leading to 100% failures instead of 99% failures, if it works, it won't work because it's tactical
combat.
