Hello! I am wondering if there are any differences between speedrunning ds1 and dsr all achievements. If so what are they? Thank you!

Hey, the best start would probably be to actually watch the two runs! But yes, there are differences, chiefly in that DS1 does not allow you to obtain some Covenant items without farming them (such as Souvenirs of Reprisal) but they do not have to be farmed in DSR due to several strategies being available - being able to Prompt Swap onto any item category at a merchant, while DS1 only allows adjacent categories to be Prompt Swapped to.

They patched dead-angling, move-swapping, and the old way of item duplication. Those are the main functional differences. imo they should've kept dead-angling in, even though, granted, it doesn't make logical sense, it was a core part of PVP for YEARS. If they patched that, they should've also patched toggle escape.
