Battle Githyanki-- layered Midori and grenadine
Undead Baldurian -- similar to Kir, I would think. A fine red with a splash of creme de cassis. Must be served in a fine holiday wine glass, or goblet.
Mystery Brew -- some mix of blue Curacao mixed with grenadine to get a purple color with...um probably gin and tonic I think for Gale. Possibly a dry champagne, given the sweet additions. Would do really well with edible glitter.
Druid's punch -- pomegranate juice with orange slices, creme de cassis, white rum, soda/champagne (I use this if I don't add rum). Garnish with sugared rosemary and cranberries. Personal favorite of mine. My friends think I'm not too far off from a druid IRL so I went with a mix I've made many times.
I was inspired by my party members. Lae'Zel gets one that's a fancy shot. Strikes me as someone who drinks to get the job done. However her blend is mostly due to color. Astarion would stick with fancy wine. I also wouldn't put him past a Brandy cocktail. I can't remember Gale's preferences so that one is more magic inspired. Then my friends think I'm not too far off from a druid IRL so I went with a mix I've made many times.
Cheers and enjoy the holidays!
