>>5277387>How do you get access to magic/fantastic powers in WoD?I wrote all too much about this a couple of threads back. This
>>4952117 will give you a pretty solid idea of what's available. It was written with 1e in mind, but they're now playing 2e. So for 2e all a mortal PC needs to do to get magic is pick up a Supernatural Merit for it. The World of Darkness is full of magic and strange phenomena, mortals having strange psychic powers or senses beyond scientific explanation is not all that weird for the exceptional sorts of people players make. So you can just become telepathic by spending the Experience required for that Merit, although a good player will tie stuff lie that into the narrative.
Outside of that there is a lot of ways, basically every major splat has a lesser template associated with it that it can create in some fashion. The major ways would be a Vampire making you a Ghoul by feeding you their Vitae, this basically makes you an addict for their blood and their slave but you do get access to some Disciplines. There are also the Proximi families for Mages, which are basically just worse Mages. You can spontaneously become a Proximus though, even if it's usually runs in a bloodline. Speaking of bloodlines you can be born with powers. Werewolves give birth to Wolf-Blooded who all come with a minor sign of their heritage, called a Tell. Not every Wolf-Blooded undergoes to First Change but the can become full Werewolves. Demons can make the Demon-Blooded, who are one of the more powerful lesser templates thanks to their inheritnace. Vampiric blood rites can make a Dhampir, who are as much children of destiny as they are of mortal and Kindred. They're also probably the coolest lesser template by a fucking mile.You could stumble into the Hedge, a borderland between the mortal world and Faerie, and end up as a Faetouched. which gives you a measure of a Changelings powers. But there are also people like the Atariya who just become supernaturally lucky. Basically a fuck load of ways, and that's not even all of them.
>Can you use parts of a monster's corpse to craft something useful?Plenty of ways to use monster bits but only one is really crafting, and that would be the Elixirs of the Ascending Ones, a Hunter Conspiracy. A lot of those use rare reagents, although off the top of my I can't think of any that are like "You need ground vampire fang". These don't have to be potions either, things incense, salves, balms, vapours, powders, and tobacco-like mixtures all get mentions. There are other ways to use monsters to gain power though.
Sticking with Hunter you've got the Cheiron Group who have the secrets of Thaumatechnology. Thaumatechnological surgery is basically transplants, or implants, of monster bits into an Cheiron Hunter , often with some electronic elements, in order to gain some sort of power. Like maybe you want to graft the sensory organs of some monster into a Hunter so they can read auras, or you give them retractable claws as a backup weapon, maybe you replaces ligaments and tendons in their legs to make them superhumanly fast. The Faithful of Shulpae, another Conspiracry, practice the art of Anthropophagy. Essentially they eat pounds and pounds of monster meat in order to gain its powers. Basically any Dread Power a monster has you can gain by eating them this way, although it's a lot of meat and it's not good for you.
The next big way is actually a whole different gameline, Deviant: The Renegades. In that game you play a human that has undergone a terrible experiment/surgery/event at the hands of a Conspiracry (Not the same as Hunter Conspiracies, although you can use them too) and as a result your soul has shattered and you've gained great powers at a terrible cost. One of the 5 "Clades" of the Remade are called Chimerics, and those are people who have had parts grafted into them. The Remade can do just about any sort of thing you can think of really, it's a body horror super heroe game where you built powers through a modular system of effects and costs. It's super fun.
Outside of those it's pretty niche things really, like there is a Vampire faction called the Ordo Dracul who are all occult science, alchemy, and the like to ascend the vampire condition. They have a set of abilities called the Mysteries of Zirnitra, focused around overcoming the vampiric limitation of being unable to acquire mortal Supernatural Merits. A side ability of this Mystery is called Grafting Unholy Flesh, and it's what it sounds like. You can take a body part from another Kindred, psychic, or other supernatural creature and surgically graft it onto yourself. You need to know the creature possesses a supernatural ability to take it, and the part you take from them must be symbolic of said ability. While it remains detatched from them they lose access to it, and for as long as the graft remains intact on you then you can use it yourself.
