kRO has a city unionification system where you gain union tokens to support your city(s) of choice in exchange for gears you can use level other characters!

/navi moc_para01 60/45Copied!

1. Go to the main room of the Eden Paradise Group
2. Register with the NPC near the boards to take your quest.
3. Hunt natural monsters to automatically loot Union Token at an approximately 20% chance.
4. Invest in 250 Union Token to an city of your choice once per day. See Union Gears section for turn in location.
5. Once invested enough, the city will begin to sell you Union gears.

Note:

• This quest is “permanent” until you go back to the NPC to abandon the quest.
• All cities share the same cooldown so choose your first city carefully.
• All party members who have the quest and were on screen when a mob dies will also have a chance to acquire a Union Token.
• Players can check the progress of each city you contributed in through achievements.

Tips:

• The first Union Gear unlock is the weapons so maybe unlock all weapons from every city first.
• If you have an alternative character on the same account, invest in a different city than your main.
• Recommended to complete one city to get EXP Gears to level alts quicker.
