The bouncers are to spawnkill spiders if your wondering

You could potentially do it with less Warden stats, the stats I put in the required was around the stats that I had with Myth Gear, a Fish and a workable weapon from Ruthless HC Halloween Spooktacular.

If your having issues you might need more Monk Range or Squire Damage, Dread Dungeon is generally for 1k stat heroes but having more stats is generally better.

I used a TB Monk on 1 and a Apprentice + Monk guardian afk summoner on 2 but depending on your stats these are probably optional.

Hint 3 is where I noticed Sharken and Djinns tend to get stuck, either wait for them to despawn or DPS them down.

If your still having issues then consider placing down some archer and mage minions via a summoner, 1k stats is probably good for that.
