"<See! I told you the black robes look creepy!>"
"<-Goth-. You said it looked goth.>"
"<Eh, same thing.>"
"<Not really, goth can look cute.>"
"<And creepy can't?>"
"<Depends on the kind of creepy. Like spooky creepy or 'windowless van in front of a preschool' creepy.>"
"<Ah! The ritual! Back to chanting!>"
The blood burns. The skeleton burns. The chalice burns. It burns and burns and burns, consumed by the same sickly green flames as the candles until they become indistinguishable, until they become the candle flame and their presence upon the alter becomes no more.
All that remains the abhorrent consequence, a thin ichor, sickly in its verdancy, its surface branded by a shallow crescent of small pellucid pustules. The stench hits you, good god that stench, it is the redolent mephitis, the olfactory intrusion, of that unspeakable virescent viridescence that flourishes in the forsaken depths of the wild and the lands that man had relinquished to its dominion, carried aloft upon the zephyr of the godless heavens. They present it to you, a blasphemous concoction sealed within a cycloidal receptacle by both the Stygian walls of its obsidian prison and by the inexorable beckoning of a land forgotten to the earth itself.
It's sort of like matcha green tea in that is literally matcha green tea.
Eh, it's decent. Just decent. You've had better, you've had worse. But hey, on the bright side there's a lesson to be learned from all this - you should totally trust creepy people in black robes chanting around bleeding skeletons! They're probably nice people who will give you tea and other free stuff!

Vessels you find, got a few options really, the sample vessels are built with safety in mind and assume whatever you plan on storing in them will maintain itself if injected with spirit energy, allowing otherwise hazardous magic to stored semi-safely in that failure would result in dissipation rather than some violent release. Forensic vessels err even further on the side of caution, storing only a faint memory of the magic rather than the magic itself. Blast vessels are just, on the complete other side of the spectrum, you need to keep them pumped with magic to keep the magic functioning but it keeps the magic at near full-power and will just release it no fucks given soon as the power's cut. There's a few more in between, depending on whether you're interested. High explosives, you'll have to decide on a blast type (exothermic, implosive, gravitational, psychic, etc.) consistency (solid, powder, viscous fluid, thin fluid, non-newtonian fluid, superfluid, ethereal, goo-like, dough-like, dough-substitute, etc.) trigger mechanism (magical, electronic, verbal, geis, etc.) and the like.
