Use a Jester with a BF Drill, any DPS Staff and as pet a Harpoon, Kraken or Mega Chicken (Snowman and Crystalline Dragon also should do fine). You can also use a DPS Monk with a Mischief Maker. I suggest playing in 1, 2 or 6 players.
Note: Mega Chicken is great to have because of its knockback bonus, which greatly avoids you getting stucked by enemies hugging you to death. So make sure your Mega Chicken doesn't have a negative knockback bonus.
