Dragon Quest XI: Echoes of an Elusive Age

• DLC/Preorder stuff is unlocked in the Misc. Menu > System Settings > Claim Special Rewards

• The game autosaves when you zone.

• You can eventually reset your skill points at church. Not only should you play around with different specs, some nodes will unlock bonus skill points.

• Some harvesting points appear only at night. Check your map to see the locations.

• Quests that require peps to complete can be tricky. You can always help trigger peps by beating on your allies with crappy weapons.

• On the final turn of a pep, you will see the aura on the character's portrait begin to fade.

• You might see little bullseye targets around the map. You eventually get a tool later to take these down.

• There's some battles where you are meant to lose. The earliest one is
  a sudden ambush on a stage taking away your party members except Erik.

• Right after the above battle you are a meant to lose, it's safe to ignore the game telling you to beeline to the next objective and explore.

• The first time you enter the Casino aim to get the 500pt recipe book. Abuse the auto-save feature and move on. Don't bother with the other prizes until the high-stake tables/machines unlock.

• When it comes to quests that require pep with multiple characters: if someone gets pepped up and you want to keep them that way until someone else gets pepped, just change your lineup so that they're in the reserve. This will prevent their pep from disappearing.
