merc best for cowing? most people say infinity merc, which is obivous (conviction + lightning DUH!), but for people who actually cow, they say its best without a merc. i myself have had all 3 difficulties of cow king killed by my infinity merc when the portal spawned too close to the king. also i agree with other when they say the merc gets in the way and doesnt allow u to herd the cows into 1 big ball as well as u would by urself. so is the infinity merc still worth it? is there an alternative?
