As you go on missions, join events, spar with others, or engage in most other activities, you will gain EXP (experience). Experience rewards are divided into categories for Missions, Sparring, and Crafting. Spar and Crafting EXP are static, while Mission EXP may be increased by the Mission Runner if you perform exceptionally. Whenever you level up, your current experience resets to 0, and you must gain the required experience for the next level from scratch.
Sparring
The first method of gaining experience is to spar with other players. You can engage in up to 5 spars per week, with a limit of 3 active spars at any given time. Whether you win or lose, the experience gained remains the same.
All spars must have a minimum of 1 scene per sparring partner, with each scene consisting of three posts of at least 600 characters per participant. Additionally, an introductory scene is required to set up the spar (e.g. 1 scene of setup, followed by 1 scene of actual sparring). Failure to meet these requirements will count as an in-character (IC) attack and not a spar, resulting in IC repercussions.
Experience from Spars based on your Opponents Level When sparring with someone of a higher level bracket, you will gain experience as though they were one level bracket higher than you. For example, if a level 5 character spars with a level 45 character, the level 5 Character would gain 10 experience instead of just 2.
