Champions Challenge

Champions Challenge is a system where you can push your character to the limit.
It works with money sacrifice, which means, the more money you sacrifice, the stronger will be the boss (and better will be the rewards).

Difficulty and rewards scales based on the amount of money sacrificed

Requirements

Bar of Gold

Rewards

Champion Points (usable on champions challenge shop)

Champion Boxes (yields items usable on gear upgrading)

Solo Sacrifice

First of all, drag the desired amount of money to the solo sacrifice basin.
Recommended starting with 1 gold bar and then raise the amount if you can handle the boss.

Then, go to Salovar NPC and speak this dialog:

Hi > Yes > Yes > Yes > Solo > Yes

After that, you will be teleported to face the boss.

Once you defeat it, your rewards will be send to your backpack.

Refunding Money

If you threw the wrong amount of money on the basin, you can ask NPC for a refund following this dialog:

Hi > Yes > Refund
