[Castlevania Netflix] What are forgemasters exactly? what makes them different from other magicaians like sypha and the crown king or alchemist like st.germain? Are they born with their powers? do they learn them?

Also how do they figure out what tools they need to invoke their powers ? does it always have to be those tools ? cause Hector brought his cat back with coins ? Also why are their magic imbued weapons so effective against vampires and night creatures and seem to be able to break other magic stuff like with Issac breaking the control crown?

Do they get to choose what kind of night creature they create or is it just at random ? Do they get to pick the soul ?  What is considered as powerful for a forgemaster?

It's explained better in the games, in particular Curse of Darkness where you play Hector.

In short, they are humans trained in dark magic, spiritual metaphysics and alchemy by Lord Dracula and were his generals during his first reign of terror. They created a significant amout of his creatures in the past out of either pure dark magic of chaos or by turning dead humans into monsters, as we see Hector and Isaac do in the series.

There is a difference between the game and the show, though. In the game, the familiars created are called Innocent Demons and are utterly loyal to the summoners themselves and *not* Dracula. We see that the monsters created by Hector and Isaac are either demons summoned from Hell to the bodies or the actual soul in a body transformed into a monster.

They also seem to employ different summoning mediums and techniques; Hector seems to be the "Put the souls of the dead back into their own corpses and make them into monsters" school and primarily uses surgical techniques and making enchanted weapons, while Isaac summons random spirits into corpses in a cruder technique as well as specialising in breaking enchantments.

Think of it like doctors who branch out into specialist roles.
