Fastest leveling duo

[Tewaz]

It really depends on what you want your play style to look like.

Some class with aoe spells with a Bard (Bard/Bard, Bard/Wiz, Bard/Druid, etc) is going to give you break-neck leveling speed, especially when the Bard hits 18.

But, you will suffer a huge lack of skill-ups, and the Bard will be running in circles with their sanity teetering and the other player will be bored out of their mind.

If I was playing with someone and wanted to level fast while having fun, I would go Shaman/Monk. Great melee with incredible buff/debuffs. You can conquer most dungeons in the game together, and each class is very powerful on its own.

If I wanted to be dominant 49+, and farm some of the toughest camps in the game, I would do Enchanter/Cleric.

It is really up to you.
