He told me I can't learn sorceries and then just didn't sell me any sorceries.

Big Hat Logan drops the White Dragon Breath Sorcery, the Tin Crystallization Catalyst & the Big Hat after you defeat Seath the Scaleless.
He doesn't just drop them like this wiki page says.
You also don't have to make him go insane like most people think you have to.

His hat doesn't drop when killing him normally. Only when he goes hollow :(

why can no one explain why his name is big hat, these comments say it's because of his humongous hat but it doesen't seem to be related, help!!

mfs shocked fromsoft would make a character called dung eater when they literally called this dude Big Hat

What if Logan actually IS the hat, and the guy is just a puppet controlled by the hat?

i ship ranni and logan..Both hat a lot in common….okay il leave now

pretty big hat ngl

accidentally got him hostile towards me, not in the mood to farm 30k souls... im not going ot use any sorcery in my first time playing anyhow

I killed Big Hat Logan while he is still not insane(note that I still have not killed Seath), after I killed Logan I go to Oswald to Request Absolution, the game said I am not sinned!?

Can someone please explain?
