The syntax will be: Legacy (Password), then it'll take you into a special prompt to ask for you to confirm this decision. Once you do, it'll ask if you want to change your village, which you don't have to. Then, the magic happens. Your character reverts to level 1, and everything that makes you, you is removed, except for what is listed below.
Once fresh from doing Legacy, you are whisked back to the start of the game, like a fresh player. Here is what is reset versus what is not in a more listly format.
Reset to what a level 1 player has:
- Stats
- Any LSC training
- Abilities
- Skills (Non-Myth)
- Being RP Authorized
- Title
- Age
- Height/Weight
- Kill History
- Favorite Skill List
- Ninja Rank
What doesn't reset:
- Clan
- Arena Stats
- Achievements
- Total hours played
- Friend's List
- Myth
- Equipment
Every time a player uses Legacy, they will receive a passive bonus to:
- Total Practices
- Total Stats
- Experience
- LSC Gaining
So, people who use Legacy will see increases to the above, to help make up for being back to square one, in some cases it might be double, in others just a small increase. Every time someone uses Legacy, it stacks. So someone who has done Legacy 5 times will gain way, way more experience than someone who has only used Legacy once or never. The ultimate goal of the system will be a way for people to put in the work to make ungodly characters like the Uchiha Madaras of the NM world.
All this said, my assumption is that the majority of players will never use Legacy even once, and that a minority will use Legacy one time, then only a handful will ever use Legacy more than once.
Edit: Adjusted things based on our discussions to be the more finalized version of this.
