teeta: Most people don't want easy to kill monsters... They want a challenge. As far as inviting new people to play BD, why should there be rewards? Either you like the game and let others know about it or you don't. The reward system actually causes cheating because some people are greedy and do their best to cheat the system. I don't believe there should be any type of reward, not even badges.

benboga: i think if we invited new ppl here they will j0in but n0t sure if they will be active kn0w why?because of the 'm0nster's rank' th0se m0nsters w/above rank 7 are hard to kill thats why newbie will never be active sir dreamer better to rem0ve m0nster ranks so the newbies will enjoy this game & they will be active i think

dreamer: Thanks for the ideas, guys. Non-refundable credits might help to solve the cheating issue.

morgana: The gift box idea is good too but i think maybe for that a random amulet and 2 rings as they are the hardest things for a new player to get and would help a new player most but given only to those invited by an active player

morgana: I think like if someone registers thru your link you get a random item and like 10 credits when the player reaches level 50 that way you benifit from each person you invite and get rewarded for realy active players

idiot_terror: This wasn't my original idea but I think it's good.

For referals, give them a 2 RP [Referal points] Rewards or Non-transferable credits that can be use only for purchasing some game features (frenzy, supporter, stamina refill, random item, etc.)
On what level? Maybe you can decide on it .

For New players, give them 2 Gift boxes recieved on certain level [One at level 20, one at level 45] that generate random item when used (depends on the character level). These could encourage them to level up and be active.
How to prevent cheating? Gift boxes can't be traded nor sell in the market at the same time, each box will be gone after 24hours, if not used.
