WHY? There are more old players to help you with your quests! To know which servers are you on, view Servers & Creating Account.
Most people are stationed at Channel 6, Old Server (奇幻大地) and Channel 1, New Server (迷霧森林).
You can earn free Green Gems through PvPs or open gift boxes. Green Gems can be shared between characters in an account. Thus, it is advisable to have 1 MAIN character and another GEM FARMER character to get extra Green Gems through opening more gift boxes and PvPs.
You can earn purple gems from Instance and Joint Activities. You can get rewards such as Bottle Pack, Wooden puppets, EXP Potion, etc to help your character in training!
So you won't regret what you build when you reach Level 100. Do not add too much WIS as you get to use Potential Pills (Given to you for free) to increase your character stats.
You can start washing your pet stats at Level 20. If you pet stats suck to the core, buy Pet Return/Lethe Scroll or get it free from the quests and make it OP. (Do keep some CONs for training purposes.)
Grab some of these from the Item Mall sales! Make yourself and your pet OP.
Keep your pets from dying so soon with more HP!
