Darkest Dungeon II

The Sluice is an optional region that can be found during expeditions after the first region is cleared (not counting the Valley). It does not count as a region itself, it is a bonus that can give more rewards to prepare you for the Mountain (or weaken you/end your expedition if you're unlucky or bad). I almost always go into the Sluice whenever possible for the extra treasures and candles. If you're carrying a plague doctor, I recommend switching from blight to melee, as the swinepeople in the Sluice are resistant to blight. Overall I would describe most swine as glass cannons. They can do high burst damage, but are very squishy. Heroes that can attack multiple enemies at once, like grave robber and crusader, will shine here. You should also bring some form of stealth mitigation, as several of the enemy types can enter stealth and do large amounts of damage. There is no lair boss here, but usually more fights than other regions, so keep that in mind. Also there is no map available in this region. Your cheevo will pop after you finish the final Sluice node and arrive at the inn.

P.S. If you encounter swine skivers (spear throwers), focus them and ignore all other enemies until they are dead. They are real bastards and will shuffle your team, do heavy damage, and apply debuff tokens.
