Full Moon definately seems nice and all, but unless you take the gold talent in toxicity reduction, even albedo seems like upping your toxic level when you could be using it on other things, and thusly getting some really nice combos like wolf/wolverine or tawny owl/marribor forest. I definately think swallow is the most useful since it's probably the potion I use most. When I'm using it with other potions, I usually pop something albedo first, and then go nigrendo for swallow. However, when I'm just running around taking on things that aren't as tough, I keep a seperate stack of albedo based swallow potions for those "one potion will do" moments. Incidentally, I'm surprised to see white raffords getting votes... I only use those when I'm in a really serious jam, which thankfully isn't often.That being said, a nice rubedo based wolverine or marribor forest is sufficient in situations where I know I'm not going to take too much damage, like fighting necrophages. I'll admit, I tend not to pop swallow in those situations.
