To become a legend quickly, - Gauntlet Dark Legacy
To become a legend quickly, complete the first two relms and battle the Dragon with the name PURPLE so you will have unlimited turbo, this will make it easier to defeat him from up close.
Continue replaying the dragon level untill you amass 999999 coins, this is the limit. Then purchase added magic, strength, speed, and armor and repeat untill they are maxed at 999.
The more players you play, the more coins that are dropped (it doubles the amount for each player).
Once you have amassed alot of coins and atributes you can speed the process by battleing the Spider Queen at the end of the forest relm.
She is harder to beat but pays twice as many coins and advances levels much quicker. I have all my characters to legend status and have only completed the game with the Archer.
I used her to get them into the level then used my new character to pick up the coins and then bought invunerabilty to defete the spider hand to hand.
