I've tried to kill Sif no less than 8 times now. There is a massive confluence of things that prevent someone from being able to beat her.
- I didn't join the Forest Hunter Covenant so now I have to deal with the mage, thief, cleric, and warrior every time I want to try her. You can just kill the mage and warrior and skip the rest but so help you if you trigger any of the other while trying to sneak around. Doesn't help that the thief is a phantom and annoying to fight. They're good for farming soul I give it that, though.
- Every time I reverse Hallow and become human and get invaded. I mean EVERY time. I've been invaded 7 times in a row trying to get to Sif while human so I can summon other players and EVERY time I've been invaded. None of these times have went well because enemies don't care about them so they just wander around the forest and wait for me to trigger something. If I try to just leave the forest they just wait to ambush me. I can't PROVOKE them into doing anything because they just wait for me to aggro or try to wait me out. I did get 1 shotted by a magic user even though I was wearing a Grass Shield with good magic resist. Argh! I know this has something to do with the fact that I didn't join the Forest Covenant but damn thats harsh!
- I've spent a grand total of 3 hours in grid-locked arena combat with Sif and I know her patterns inside and out. I could draw you a map of every telegraph she has. The reason I can't beat her is due to the horrible framerate drop that happens while playing her. It isn't Blighttown levels but its worse because her attacks are so fast that even a moment of lag can kill you. I die in two hits so I have to heal after every video lag that gets me hit. The lat is SO bad that if I wait for her to do her whirlwind attack so I can heal myself with flask or miracle. I've seen it as bad as a full 5 seconds after the attack is through it will finally kneel and heal. Doesn't seem that bad with a flask but thats still ridicules that its actually the framerate drop that is killing me. Sometimes my attacks won't even occur because the game is lagging so bad that I think it stops accepting controller input. I had her down to where she's limping and the game lagged and the shield block didn't animate/occur and I died.
I swear I think my apartment neighbors thinks I'm a wife abuser!
