In Old School RuneScape (OSRS), a full account reset isn't possible. However, depending on your goal:
1. Restart a character: You can create a new character on your existing account, essentially starting over with stats and progress.
2. Ironman/Ultimate Ironman mode: Begin a fresh challenge with limited interaction with other players through these game modes.
3. Specific skill resets: Utilize quests or items to reset individual skills like Hitpoints or Prayer for focused training.
While a complete account wipe isn't an option, restarting characters, exploring different game modes, or resetting specific skills offer ways to refresh your OSRS experience!
