Farming Alpha wolf rug is hard for me

[Lawpvp]

Ive killed this thing 32 times and only gotten 1 out of 3 spirit relics that are needed to craft it. In my last 26 runs ive gotten 0. Somebody I met while farming got all 3 spirit relics in 18 runs. How can the rng vary that much. 3 in 18 compared to 1 in 32. And ofc there are jarl relics and hugal relics in auction but 0 for alpha wolf. If anybody has any to sell i will pay u for them
