I also vote for swallow, in the act 1-2 in mush useful atleast it help you to make an advanture without attaining too mush on campfire. Fullmoon, for me I think it come pretty late because when it appears my Geralt are too strong and don't need it any more, further more I hate when I have to wait for my vitality to reach it double time so I usually need to drink it with swallow any way.Blizard I hate it ! I will drink it only nessessery, yes it help you mush in combat but it slow you down all the time and that F__king annoy me. (I drink it once in act 4 and go to play a dice with a gambling ghost, you know the dice game are slower also). White raffard It should be useful but I foud out that I don't need it also. Because my Geralt (str.Gerat) never loss a vitallity than 25 percent so I rarely use it. So, only potion that I think useful all the game is swallow and it MUST be drink whatever youy Geralt are so I think it is no.1 potion
