(Hollow) Oscar, Knight of Astora is an Enemy in Dark Souls.
Oscar of Astora
The remnant undead form of the knight who gave you the Estus Flask in the tutorial stage. When you return to the asylum you may see him walking around but beware: he is not the same man he was the first time you met....
- No special strategy is needed. Engage, dodge, kill. Parrying is easier when he fights one handed. He also is overburdened so whenever he rolls, feel free to wail away
