The 'Irresistible Thirst' moodlet is now called 'Bloodthirsty'. The Parched moodlet's description has been changed to be more straightforward, and will now appear when the thirst needs drops below -75.
I thought it would make more sense for vampires to drink ''plasma'' in order to survive. This mod makes it a vital necessity like in the previous game. I didn't like how drinking 'plasma' was just something that made vampires happy and comfortable. Your vampires better stock up on sanguinary sustenance, because if their thirst bar depletes completely, they'll be putting the 'dead' in 'undead'!
