The Training Grounds, a place of survival and victory.
Can be entered through the Konoha NPC Shiranui
There are four battlefields in the Training Grounds. On initially entering the first battlefield, three different quality keys will be produced, copper keys, silver keys and gold keys. There are also three different guardians protecting treasure boxes - the guardians of copper treasure boxes, the guardians of silver treasure boxes, and the guardians of gold treasure boxes. They are distributed in second, third and fourth battlefields.
Defeating an opponent will award the key shown above that opponents head, while while also increasing your victory count and victory points. In any battlefield (excluding the 1st floor battlefield), once the total number of defeats reaches two, you will be returned to the former battlefield through the portal, where you must obtain again the required number of victory points to progress to the next battlefield.
In each event, the first defeat of a Treasure Guardian will award additional rewards.
At the end of the event, if a keys remain unused, a key of the highest owned quality will be awarded for the next time the event is entered.
Ten minutes after the event, the events ranking board, victory points board and Fastest Combatants rankings will be generated.
