If you're a new player, I recommend not to spend gems unless you really have to. For example: since you can speed up the process of crafting stuff by spending gems, don't do that, even if it takes 1 millisecond and 1 gem. I'm patient, and I don't speed up crafting time.
does anybody know this problem i have: i've donated tens of thousands of coins to my guild and still haven't gained a guild level. does it just take a crapload of coins to level up your guild level? i'm guild level 96
some of the bosses in this game are impossible to kill with one player. for example: king of unliving dead has 4,000,000 hits. i use to play adventure quest and it's like that too, that some bosses are impossible with one player.
this game would also be awesome if there was an arena and optional bosses, bosses so powerful you couldn't even be recommended to fight them until level 300
