FAQ
Q) What happens if I die?

Your points and progress will be saved. You can simply go talk to your mentor to have him warp you to the training room again.

Q) How can I prevent dying?

Have 100% neutral resistance and 100 MDEF. You can also use restorative/healing items such as Yggdrasil Berry and Royal Jelly or Green Potion (from Street Dealer).

Q) How many points do I need?

Your ultimate goal is to earn 100,000 points in order to get your Odin's Blessing, but you can achieve this whenever you'd like. =)

Training Approach
The One trains by killing/defeating monsters in a separate arena filled with monsters at three different levels. The monsters get harder as you move on and it tests your patience and determination. Note that you may rely on autocasted skills, but you are not allowed to leave your character unattended. This includes leaving ExperienceRO minimized while you are on another window. This is considered as AFK farming which is against the rules.
 * Level 1→2: 10,000 points
 * Level 2→3: 40,000 points
 * Level 3→4: 70,000 points

Level 1
100 MDEF and 100% neutral resistance is recommended. You can use Wings of Hail or Wings of Storm against them.

Level 2
You can use 100% neutral resistance, 100 MDEF, and Wings of Hail. Wings of Storm's wind property is not effective against the Wind dragon.

Level 3
As usual, you will need 100 MDEF and 100% neutral resistance. Wings of Storm's LoV works against all the monsters except for the one that resembles Sniper Cecil/Cecil Damon.

They could silence you, disabling the use of skills during the status's duration. You can, however, use Royal Jelly or Green Potion from the Street Dealer to cure yourself.

Mentor
Kenshin Himura: Moonhaven @jump 275 85. Do note that you'll only start getting your respective Path points after talking to your Path's Mentor.

Seals
Seals are ingredients used to make items at The One Keeper. You will get either a Seal of Endurance or a Seal of Consecration at every 5,000 points (at a 50/50 chance). The Seals also correspond to the number of Seals you have in your inventory. Let's say you're at 10,000 points, but you have 2 Seals in your inventory somehow, your next Seal will only be given to you at 15,000 points.

Keeper
The One Keeper is found at the right side of moonhaven (258 194), where all the automated event NPCs are located.

Pinnacle
Pinnace: 100,000 'The One' points.
