@Achronum My thoughts on blood tastes:
Fire: Typically taste of something smokey and rich
Earth: Taste lightly Spicy, like cinnamon and chili peppers
Wind: Tastes light and cool like strawberry ice
Water: Tastes of bitter made sweet, like sugary teas
Ice: Tastes bubbly and sharp, like champagne
Spirt: Tastes of a thousand different things, like fruits, tangy, sweet, citrus
Electricity:Taste of sour, like lemons and grapefruit
Darkness: Taste of the finer things, like steak, red wine, dark chocolate
Light: Taste light, like cream and berries and happiness
Metal:Taste bitter- Like Black Coffee and Turmeric
Humans: peanutbutter.
Like...the blood equivalent. I don't think anyone will actually taste like grapefruit.
