User blog:Blalafoon/Blala's Guide to Efficient Character Growth

Early Levels: 1-15
Make sure to work your way to achievements as they are easy money.
 * 1) Enter Hyperbolic Time Chamber for one hour.
 * 2) Battle repeatedly with your opponent. If no opponent available, purchase an Easy or Medium bot from the Capsule Corporation Training Hall
 * 3) Enter any training slot while you sleep.
 * 4) Continue battling until you can enter the Hyperbolic Time Chamber again.
 * 5) Repeat.

Mid Levels: 16-40
If you have not purchased a planet yet, you should consider purchasing or sharing one with another character, as the benefits are well worth it.
 * 1) Buy Max HP potions from the shop, for either you or your opponent, increasing your HP each match, thus rewarding more HP.
 * 2) Battle repeatedly with your opponent. If no opponent available, purchasea Hard or Extreme bot from the Capsule Corporation Training Hall.
 * 3) When your partner is no longer willing to fight, work at any work station.
 * 4) Repeat.

High Levels: 41-75
If you have not joined a faction yet, you should consider joining or creating a faction, as faction bonuses can help you fight, train, and work better.
 * 1) Battle repeatedly with your opponent. If none available, fight a fleet of Extreme bots from the Capsule Corporation Training Hall.
 * 2) Participate in saga's or boss battles as frequently and as strong as possible. By this point, even if you die, Other World will have amassed a wide array of fighters who have been doing nothing but training for you to farm with, and you will likely be revived before you reach the level cap.
 * 3) Repeat.

Endgame Levels: 76-100

 * 1) Participate in mass events with lots of fights with strong characters (WMAT for example), where there is no chance of death, and hefty reward upon completion. If there is an event in other world, find a way to get there, even if it requires death.
 * 2) Participate in saga's or boss battles as frequently as possible.
 * 3) Battle with an opponent if you can.
 * 4) Repeat.
