Yes. Very yes. For those of us already working in necromancy, this is an obvious and easy yes. For those of us inhabiting the love and death niche specifically--you already know you want it. "Adored by powerful and erotic spirits" is right, and if you know, you know. The entity in your life that comes to mind as you peruse the listing? You think they'd like it? You're right. Go for it.
For everybody else, I'll note that Roses for the Dead has a variety of potential uses. Dress candles, anoint objects, mark any offering as the gift or invitation it is. If you want in on spirit or death god work, I'm sure this formulation will get somebody's attention right quick. Potent, powerful, sets the tone. It's polite to show up with a present when you're visiting someone's house, isn't it? And rude to only call when you need something, and smart to show that you know the rules. Always have something to offer.
I'm positive this appeals to a wide variety of spirits. I'm sure it's fabulous for La Santa Muerte and her devotees. I'm certain most death gods will dig it. But for me? My specific purpose? I'm using this with offerings to The Baronโnot so much to get his attention, but to show my appreciation and affection many years in. For that, I know Roses for the Dead works very well. So even if you're well established in your arrangementsโdo something nice for your friendly death aligned favorite. Show 'em some love.
Useful for the neophyte, useful for the seasoned practitioner. Powerful and comes with cute little reaper bottle art. What more is there to want?
