Here are some ideas :
- Unlimited Flash Jump/Aerial Strike/Hammer (paladin 4th job skill)
- Unlimited buffs
- Training rooms but the players must pay an amount in order to enter
- Move common equips such as zakum helmets and gloves to reward shop
- Increase the cost of NX
- Put a vote point system, points could be traded for erasers, 1 point 5 erasers for exmaple.
- Player's hideout
- Add GM, Chaos and White scrolls to reward shop
- x2 Rates on weekends
- Move Level 110 items to reward shop
- A pet seller, since evolution rock does not work
- Cloud farming, for example collect 1000 clouds and trade them for 5 erasers.
- Rock Paper Scissors NPC, For example, If you win 5 times without losing, you get 1 eraser.
- Auto Server restart to reduce lag
These are some of my ideas, and hope it helps
Thanks
