Ways to Train your Neopet

Laboratory Treasure Map

Very, very usefull! It can raise any stat, but it can lower any of them. If it goes lowers one of your stats, you can still raise your strength, defense, ect. However, be warned, it can change your Neopet’s appearence . But who cares when you can have unlimited stats at your disposal? To be able to use the Laboratory, you must buy ALL 9 pieces of the Laboratory Treasure Map.

Coltzans shrine

This is easily the best way to level up in Neopia. This shrine can give you a stat increase, Neopoints, level increase, or items.
Location: Lost Desert

Kitchen quests

This is another good way to level up. If the total cost of all the items that you must get are below 2,500 NP at any level, do it. Several levels later it is the most useful, as it will cost 10,000+ NP less then what it would cost to go to a training school.

The Acadamy

I find it to be pretty useless. It only cost’s less then the training acadamy when your Neopet is at level 1-10. After that, it costs more. Only do it if the cooking quest costs alot of money. One downside is that it can’t be used past level 40. Also, it takes 4 hours, 2 more then the Training School.

Training School

Very useful, don’t use it at level 1-10. Afterwards, it will cost less then the Acadamy. Plus, it’s 2 times as fast and can be used from level 1-250.

Terror Trove Scratchcards

If you’re lucky it can raise your Neopet’s level, but its kind of based on luck. You get a level up about 1/8th of the time. Only use it if you need to raise your level and you can’t increase the other stats.

Guess the Card

a cheap way to raise intelligence is to play the Guess the Card game, you rarely get an intelligence upgrade, but it's only 10np to play, and if you play the same card about 20 times in a row, chnaces are pretty good you'll get atleast one intelligence upgrade for only 200np.

Faerie Crossword

Playing the Faerie Crossword will occasionally give your pet at least one intelligence point. It does not seem to be restricted to lower intelligence or lower level pets.
