if you want to do a almost one shot combo with this, here's what you have to do. first, you need to learn about weapon moveset swaps. what that is is basically if you are fast enough, you can make any weapon swing as fast as a dagger. I reccomend looking it up on youtube if you want to learn more about weapon moveset swap. the combo uses dagger moveset on astora gs, and dagger speed astora can combo into weapon art for a 1000 damage combo. its best to use this combo when the opponent is close to wall, because if the the angle is not right, the weapon art won't hit them. the combo is very inconsistant and hard to land, but when you land it, its so rewarding.
