Sluice Forest

When you enter Sluice Forest, you'll find it's not very big, but the enemies here can be brutal. From the entrance, simply walk North to find the path to the next area.
Once you reach the 2nd area, walk North, but stick to the left.
You'll shortly find a chest holding a Vigor Ring.
From here, walk South a few steps and then go East, always going North when given the chance.
You'll come upon another chest holding a Star Light.
Take that, and then walk up and you'll see the exit to your North.
Pass it for now and continue West to find the Warrior Crest.
Now walk back and head up to the exit.
This will put you outside the Water Ruins, on the tail end of Sluice Forest. Walk up to the bridge of stones, and Ruby observes it's underwater. Lemina says it's too cold to swim across, but that the Floodgate will be opened in the morning. Ronfar suggests camping. Good idea.
After some quality bonding time, everyone falls asleep.
Hiro however is restless and wakes up in the night to discover that Lucia is gone. Walk up to the bridge (after "talking" to everyone for a good laugh) to find Lucia is skinny dipping in the lake. ^.~
Once the movie scene (again, ^.~) is over, they both go back to sleep.
When morning comes, Lucia and Hiro have a rather funny moment...
...and then Ronfar hollers that the bridge is clear.
Cross the Bridge and exit the Sluice Forest. Head Southeast to Azado.
