The best way to grind out dungeons is to make friends with other players, particularly those with a higher level than you and take them as companions into dungeons. The other (easier) option is to join a guild, as you can add guildmates to your team without having to add them to your friends list. Being in a guild also earns you honor points, which can be spent on items in the guild shop and so free up your gold for other uses.

then you can play with friends who are a higher level than you, set your character to be last and then enemies cant attack you.Set level to AUTO & x5 speed, after a while they will earn you: xp, coins, new pets and rare or better items..

If this has helped you, and you want more of these guids, write to the comments what to make next, and of course leave the rate up
