There was a thread not long ago where ppl were saying that 100%ED is useless in arena, because +5000ED is a lot better:
But I will be replacing my ring and vial with ones that have +225% Luck, so i can replace this blistering with blink proc like @f00kee said.
I am using a Slime, but I think I will switch to Lilith since i need Faun’s gifts. All my other pets are a joke.
