SMITE

As Danzaburou, fill up all 4 Dubious Savings money pouches in a single match.

Dubious Savings is Danzaburou's passive ability. Every time Danzaburou actively gains gold, he stores 10% into one of his money pouches instead of having direct access to it. When a pouch is completely filled, Danzaburou gains bonus gold and a permanent Physical Power increase before switching to a larger money pouch. You actively gain gold by killing minions, jungle camps, objectives and enemy gods.

There are 4 money bags to be filled. The first requires 80 gold to fill, the seconds needs 140 gold, then 200 and finally 300 gold for the last two. Conquest may be the best game mode for this, as you'll be able to farm efficiently and get all that gold, but really this can be done on any game mode with basically any build as long as you farm camps, minions and get god kills.
