Mentor System

At base level 130 you can start to mentor others using the Mentor System, accessible from your Friends list. You can also cap on someone's portrait and choose Enroll Student to offer yourself to them as a mentor. As your mentors complete daily/weekly objectives you receive mentor medals which may be exchanged for the following notable items:

• Mora Coin (25 each)

• Pet Adventure Coupon (60 each) - Pet adventure consumes no stamina

• Monster Records (60 each) - Instant complete a monster lab for no stamina

• Meteoric Chain (20 each) - Uses 4x combat time for 4x the drops

• Mentor’s Potion (60 each) - Gives you 30 minutes of combat time, up to 60 daily

The best option here is mentor potions since you get up to another hour of full grind time a day. Hardest part is finding others who actually play the game to give you medals but this is very advantageous for your daily zeny gain. Most people create alternate accounts solely to finish dailies for medals on their main character.
