I have a T11 pet with 4 wins but not a whole lot of weapons. I referenced this thread and I'm not sure if I just need to get super lucky for that 5th win or if maybe I could try something else

My current setup is this:

x2 x2 x6

I use a Dark Magma Potion every turn since she doesn't block it or a mix of pylonics as needed. I don't have many other useful scrolls available but I do have these other weapons:

[edit] Big thanks <3

Devora does a lot of light, dark and wind. I used a light blocker and a dark blocker. Have you tried Gelatin Slayer and either Maniacal Tooth Sword or Blessed Trident instead of Paintbrush Blades? That may help you get the 5th win since you'll be blocking more damage.
