Experience

In NGU, EXP, aka experience points, are the currency used to buy various permanent upgrades to improve players abilities.

NGU energy and magic power, quantity (cap) and regeneration speed (bars) require a balance, and this balance can vary depending each player's game play. As suggested in the in-game help, start by getting some energy speed. Around boss 17 or so, you should be able to gain enough EXP points to also buy some energy power. See also the newbie guide for more details.

Gain Experience

Experience can be gained from several sources:

• Defeating bosses
• Random drop for defeating enemies in Adventure Mode
• Reward for defeating enemies in the ITOPOD
• Reward from item completion bonuses
• Completing challenges
• Yggdrasil Fruit of Knowledge
• Money Pit random reward
• 4G's Sellout Shop (not recommended)

Experience gained from Bosses and Titans can be increased by:

• Completing 24hr Challenges
• ITOPOD perks Bonus Titan EXP! and Bonus Boss EXP!

Experience gained from all sources can be increased by:

• NGU EXP
• My Red Heart  
• Fibonacci Perk level 987
• EXP Gold Digger
• EXP Hack
• Wish number 61 : "I wish I was more OP"
• Consuming meals through Cooking

The formula for total experience gained from the above (without the last perks is):

$exp(amount)=\left\lfloor amount\times NGU_{\text{EXP}}\times MyRedHeart\times Perk_{\text{Fibo 987}}\times Digger_{\text{EXP}}\times Hacks_{\text{EXP}}\times Wish_{\text{61}}\times Cooking_{\text{EXP}}\right\rfloor$
