Update 2/11/17

Leveling bosses are now in their near final form:

There is a max level that you can be otherwise you cannot enter the area.

There are four areas in total, max levels to enter being 6, 16, 26 and 36.

If you level up past the max level while in the area, an option to delevel is available.

Bosses are associated with each area with boss rewards.

Hope you enjoy, please let me know if you find any bugs

sweet!

Any chance you could elaborate a bit on the topic leveling bosses?
- What are they?
- Where can you find these?
- Can you solo these?
- Is it a new concept to the server or has it always been there and I've just killed them unknowingly of their concept of being a leveling boss )

Cheers,
Jaq

The locations are on a billboard in oasis resort next to spell changes, this is in the 1.69 server.

You'll likely need a group to complete them or a dedicated build if completing them solo.
