The key on making extra Tibia Cheats is all the quests available to you. Check the website to see what quest is available to you. And you are aware of level requirements to make sure you complete them before you are over leveled.
Here are some tips that will help you.
1. Make sure you pick up every single drops on the ground. It might not help you earn tibia gp, but if you do this a lot, it will be worth your while.
2. Take care of scammers. Before buying from vendors, you make sure to check the nap shop and see how much they are selling items the vendors are selling to avoid being tricked.
3. Any class can set up vendors to sell items. If you want to sell items, you can use the auto price as a guide.
4. Once you run out of healing items, you can restock on shops or if you want to be stingy, party with a muse who can heal or sit down and wait to recover.
5. No matter how evil the vendors can be, they can also be useful. Some vendors sell very cheap items below nap price that is worth buying. If you are planning to buy anything especially expensive items from nap, make sure you look around for vendors who sell them with lower price.
