went ahead and introduced the three NPCs, got a bit lengthy xP

[quote=Yog Sothoth]
then why are the most famous Slytherins known for other types of magic? Merlin is known for being extremely powerful and a specialist in charms, Voldemort has never really used any potions except the one that gave him a body, and he mostly uses dark magic. I'm not saying potions aren't powerful, it just seems like JK Rowling never really showed any Slytherins who were the most famous for them. even Salazar Slytherin is said have been a specialist in Legilimency, and deosn't mention anything about potions.

Okay, you're simply assuming those are the only Slytherin's that were ever famous. Sure none of the ones mentioned out there were 'famous' for potions, but its a big world.
