Lucky Chain Letters

Lucky Chain Letters are non-tradeable items that you accumulate throughout your journey, whether by questing or as event rewards. The only reliable way to get them is by doing quests: you will have a total of 40 by the time you are done the Mysterious Saloon questline. They are usually given to you near the end of the main questlines that span levels 100 to 120:

• Dallas (5)
• Detroit (5)
• Aztec City (6)
• Lijang Women's Village (6)
• Bulguksa (6)
• Jiuzhaigou Ghost Town (6)
• Mysterious Saloon (6)

Lucky Chain Letters can be traded to an owl dude named Chain Letter Brody. He is located either at the Rome Gate or in Antillia. In exchange for your Lucky Chain Letters, he will give you items called Rebirth Tokens. Unlike Lucky Chain Letters, the Rebirth Tokens can be stored in your warehouse. There is absolutely zero reason not to convert your Chain Letters to Rebirth Tokens.

What are Rebirth Tokens for?

Chain Letter Brody will lend you some gear for a certain period of time in exchange for your rebirth tokens. "Brody gear" as it often referred to in-game is available for all gear tiers level 140 and below.

• [Event] Lv. X Armor Box: Contains a full set of +4 level-appropriate armor, including chest armor, pants, gloves, helmet and shoes. You can pick a Magic, Melee or Ranged set. Does NOT contain an offhand (shield, orb), so plan your budget accordingly.
• [Event] Lv. X Weapon Box: Contains a +7 level-appropriate weapon of your choice

Some notes about Brody Gear

• It lasts for 30 days from the date you first opened it, even if you do not equip it
• Each box costs 10 Rebirth Tokens regardless of level
• You cannot trade it, dismantle it, enchant or enhance it
• You can equip it on your mercs

Other stuff you can get with Rebirth Tokens

In the event that you do not want/need Brody gear, you have the option to pick for one token each:

• Water of Life [Event] (No Trade) x1
• Resurrection Scroll [Event] (No Trade) x1

My recommendations

Save your Brody tokens for level 120. They will be extremely useful when you do your upgrade quest, and they will also serve you well for the level 120 TBS missions. Since the level 120 upgrade quest is insanely expensive, Brody gear is a good way to outfit your main with pretty decent gear and save up your money for the upgrade quest. An armor set and a weapon will cost you 20 Rebirth Tokens. You can repeat the process once you get to 130, since Evil gear is quite costly.
