Calm down, we will have our jinchuuriki treasure. We are around 2 months behind germany so i'd say 1st week of july.

For the guy above, you get 1 point for every 10 ingots you spend. 50 ingots = 5 points.

The ingot count is simply an ingot count. To keep track of how many ingots you have spent during the event.

What matters is the counter to the left which indicates points.

You do not spend ingots directly on this event. This event rewards you for spending ingots elsewhere (gift pack special offer for example).

You spent 330 ingots so you were awarded 33 points extra points. You used them to exchange for either 3 keys or death hidan frags (from your image).

Hope this made it a bit more clear on how this event works :)
