Guys help! I'm close to throwing in the towel here. After over 100 hours of fun I'm on the verge of giving up.

The aforementioned queen of pain has killed me again and again and again. In fact I could swear she's killed me more times than everything else in the game, combined! I've summoned everyone I can, no dice. I've used over 20 human effigies, still nothing. I've played so many times I even got the little piggies once. And yet still I died. So if there is anyone out there with some foolproof tips on how to take this game killer down, I'm all ears.

Alternatively if there's anyone out there who wants to jolly co-op her ass back into the abyss, hit me up. I'm playing SOTFS at Sl 15 mil (or thereabouts) on PS4. I'm also in the UK so timing wise I'll be around at about 19.00/20.00 GMT tonight.

Help me DS2 community, you're my only hope!

Edit. I did it! So taking various people's advice I increased my agility, upgraded the red iron twinblade, used gold pine resin, and went at her one on one. Two tries and she bit the dust. Thanks all of you so much, I couldn't have done it without your help.
