1. if you purchased Gold go to Asgard and talk to this NPC:
you can give this NPC 1000 silver, 12 gold and 120 gold. Each amound can just be used a single time per account. Giving the NPC the mentioned amounds rewards you with a chance to get it back by 2-times, 5-times or 20-times you will ALWAYS get the silver/gold back plus ATLEAST 2-times of what you spend.
For example: You give Saga 1000 silver, then you will get the 1000 silver back + the chance of getting 2000, 5000 or 20000 silver. Its a bit different with Gold: you will get the gold back that you paid + a chance of getting x2, x5 or x20 of the amound as VOUCHERs!
So you better use this chance! you will get something for sure without losing anything at all!
2. Dont waste your gold for stuff like guard exalts, guild order or even costumes because they give additional stats! Your gold is better invested in "2x Trial Cards" which grants you double exp and double drops in trial Tower, and "Fairy Grass" which you will need for your mount to upgrade it faster (unlocks at lvl 39). The Mount gives you with every lvl bonus stats on the 4 maintstats (agi, int, str, end). with fairy grass the mount will raise very fast which gives you alot more bonus stats then the current customs would do with less gold invested.
3. do NOT purchase gold through Facebook!! Facebook charges much more then gamebox itself does!
example: Your buying on Facebook 70 gold for 10$. On Gamebox your paying 10$ for 100 gold. Chaos Rage Gamebox (Facebook name) and Chaos Rage on "cr.gamebox.com" are the very same games with the very same servers. So why paying more then you need to?
NOTE: this are merely tips and tricks to give a certain guidance torwards new players. You may or may not agree to the stuff above or do want to play it in a different way!
There are still many many more things to learn and to do, yet this is, as mentioned, merely a guidance. not a FAQ. Use this guidance as a base and learn how this game works by playing it. Then you will also figure pro-knowledge sooner or later
