how they smell
diluc
I feel Diluc would have a mix of three things: Pine, spruce and a faded scent of wine from both Angels Share and Dawn Winery. Sometimes you may pick up on a rich oud wood and frankincense, its a tad bit spicy but it smells as if it was a fireplace. The light smoky embers mix in with the ‘fireplace’ theme, giving a feeling of warmth and comfort.
kaeya
Kaeya probably has light cologne on, something soft or spicy. I can imagine him having a scent of smoked vanilla bean, maybe a bit of wine from when he drinks alcohol?
venti:
Venti definitely has a sweet scent, something floral. His smell definitely has a base of vanilla, sugar and honey. Maybe some bourbon and a hint of lavender. If it’s not completely sweet, it can be white jasmine: bergamot, muguet, rose, and white musk with a small note of lemon. Overall, sweet and relaxing.
zhongli
Zhongli has an invigorating floral scent. It blends citrus notes, musks and wood notes for a sparkling, rich scent. It’d be warm, some green tea or earl grey tea smell lingering. Eranium, Pepper, Lavender, Patchouli, Vetiver and Ambergris give a classy type of fragrance, a bit strong, but it works.
xiao
Xiao has a sweet, honey and almond scent from the almond tofu offerings given to him. I feel Xiao would smell like ylang ylang: heady, sweet, radiant heavy floral odor with spicy notes of clove in the background. It’d be something warm and sweet, a tad bit of spice. Honestly, very comforting.
childe
I assume Childe has a cool, beach-like scent. Light scent of salt, heat and ocean air. Maybe something like Ocean Pine, tad bit of balsam with a woodsy and floral scent. If it’s not a beach scent, it’s a rich, fruity scent. Citrus and herbs, maybe?
razor
Probably a natural scent, a scent of multiple coniferous trees. Pines, firs, cedars and cypress are examples, so a woodsy scent mixed in with the surrounding environment? Herbs, plants and a faded rain scent. I assume wolfhooks are sour, so there may be a small hint of a soft, sour-like smell.
chongyun
Chongyun would have a cool, light scent. It would probably be linear, the top note shows little variation from the bottom notes, but it’s not dull or uninteresting, either. Chongyun avoids spicy and hot things, so the scent would be faded. Cold, misty type of thing? Something ozonic and earthy, but not strong. Ozonic would be watery-airy freshness while earthy is something humid, though, I imagine a lingering, icy scent. Maybe something with warmer notes of sandalwood, cedarwood and light citrus mixes.
xingqiu
Xingqiu probably has a scent of old books, or books in general. Maybe a small scent of lavender and vanilla, or even a scent akin to that of a library's: rosewood, oak, tonka and oud - a woodsy, musky and warm scent.
bennett
Bennett has a distinctive smell from his many adventures. He smells of smoke and wood along with clove, amber, sandalwood, and patchouli. Bennett sits by many campfires and is always outside exploring, so he definitely has a natural, earthy scent. Maybe a small, sweet smell from marshmallows and a bit of charcoal.
