Hi. I posted a quick-and-dirty playtest of this with a VpEE:
https://www.youtube.com/watch?v=uPRRJAQI8JoA few thoughts:
1) I can go from bloodless to alive while in bat form. I then get to move (or do something else) while in bat form, and
only then do I get kicked out of bat form. This feels weird and inconsistent with other similar effects in the game, which AFAIk knock you out immediately.
2) You might want to rethink the edibility of monsters impacting our aux attack. It seems odd to me that this new system still tracks whether or not a monster has blood for butchering purposes even though we can't butcher/make potions of blood anymore. What I mean is that we still can't use our fangs on a hornet or a bee or other such monsters. I might be mistaken on this, feel free to let me know.
3) Throughout the playtest I experienced the same problem others have reported where I'd automatically go Alive while resting, but not automatically go back to bloodless. I believe you said this is not the intentional behavior. For me, I macro'd my space bar to "5," which I can't imagine would effect it but maybe it does. If I had gotten to experience the intended behavior during my game I don't think I'd have any complaints at all about the overall smoothness of the transition system. As it stands it was slightly annoying to switch back to "bloodless" every time, but not so bad.
4) Addendum to (3) is that it feels like there's almost no reason to bother being alive, ever. The benefits of being Bloodless far outweigh anything Alive has to offer. I can think of a preciously narrow window of things you'd want to be alive for - holy pan, the first three experience levels where you don't have batform yet, etc. Using the "Alive" regen was convenient for resetting some fights, but the same effect could be accomplished more optimally by just turning into a bat and flying to another staircase. My point is that the Alive state needs some kind of added benefit for it to be worth using. Honestly, I'm with some of the other posters who have suggested to get rid of states entirely, make vampires "bloodless" 24/7, and give them no regen next to monsters and perhaps for some time after seeing a monster. Keep the vamp drain fang attack - that can be their "flavor" alongside their aptitudes.
Edit to respond to some feedback below : The holy pan thing wasn't to avoid holy damage, it was because there's no torment in there so you'd probably rather be regenerating fast than be immune to torm. Regarding transmutations, yeah - I like that it's more viable now and it is one of the rare situations where being Alive all the time is better than being bloodless all the time. My point is that barring rng luck (finding a zerk item etc) or a very specifically designed character (VpBe, VpTm, etc) it seems like you'd just always want to be bloodless.I don't really expect a response because you outright told me you were going to give me the silent treatment awhile back and have largely followed through on it (lol) but nevertheless I hope that this feedback and video are valuable to you.
