Gains and Losses
Playing the game will earn EXP stats. Just play, and you'll gain in stats.
Being AFK will cause your EXP to drain.
New players EXP stats will, sometimes rise to high levels in a short time.
As you continue to play, your stats will fluctuate less and steadily increase/decrease.
Being offline for 5 days will cause a reduction of approximately 20% every day.
Stat Definitions
The idea behind the way exp is calculated is simple: Experience is measured by your overall activity over a period of time.
The command to view your exp stats is /exp, or of another player /exp username. This will show your stats:
OT: Every second counts. Being online in-game will increase your online time (OT)
AP: Action points. Doing stuff, even running in circles will increase this stat.
Exp: Experience gained by doing things in-game.
Level: Bragging rights, shown as nametag flair in public chat.
Luck: Chance of outcome. This number is variable, and used to determine outcome from random events (either good or bad). In other words, "whether you win or lose".
Fortune Outcome multiplier. Fortune is complimentary to luck, and decides "how much you win or lose".
Levels
Your level is shown as part of your public chat nametag flair in round brackets.
Luck and Fortune
Luck and Fortune can be used as Multipliers or Determinators for certain events.
Luck is always changing, and will never go above 1. - Used to multiply Blue Diamond drops - Used to determine EXP loss on dying
Fortune will normally increase, and sometimes decrease. - Used to multiply Pink Diamond drops - Used to calculate total amount EXP lost on dying
Bones
Dying will cause your player to drop items into a bones block.
There is no loss of EXP from dying, however using the command to return to bones may cost some EXP points.
To test your luck and return to bones, use /bones after dying.
If you're lucky, returning to bones will not lower your exp stats.
If not, your EXP will be deducted using the formula: (AP * Luck) / fortune
Regardless of how much EXP it would cost, there is a minimum of 100 EXP to use the command.
If you die in someone else's protected area no bones are dropped, and are therefore unable to use/bones.
