While this may be old news to some people, Dragon Nest 2.0 will no longer have suffixes and potentials for weapons and armour, instead; a new system known as the "Dragon Jade System" will be implemented.
Furthermore, Dragon Nest's level 70 cap a.k.a. Dragon Nest 2.0 also includes some other new features to the game, including:
The Auction System (you can now put your items on auction and the highest bidder will receive the item which marks the end of the "S> [insert item here] BO NONR No Noob" days.)
Talisman (not sure what this is about, but it seems as though they are, basically, heraldries/suffixes.)
New Accessories (of some kind)
5 New Abyss Dungeons (Sand Sea, Lost Moon Desert, Golden Steppe, Bronze Forest Path and Lunar Eclipse Canyon.)
Higher-Grade Gems (for level 70 gear)
New Fairies (probably like the dogs/cats/manticores/etc. that can give you some extra stats.)
Enough babbling! Let's get to the update's features!
