Tips and Strategies
Pick Up Side Quests
You can start picking up side quests from Residents at Colony 9. There is no limit to the amount that you can take on, and many will be completed naturally as you play the game, so do not miss the opportunity to get them all!
Talk to Everyone
Most people will give side quests, and a lot of those that don't give side quests give you area affinity if you talk to them. Every NPC with a name is worth talking to in Colony 9. These NPCs can also be used for trading.
Do Not Fight Every Monster
Not all monsters need to be defeated, and some are outside your capability. If a monster is more than 1 or 2 levels higher than you at this stage, you should run past them and come back when you're a higher level, or grind experience then come back.
