Wisdom Medals
Wisdom Medals increase a hero's loyalty by 30 when rewarded and is used for hero persuasion.
They can be found in high level valleys 7-10 or level 5+ NPCs.
Personnaly I collect all my wisdom medal from NPC level 5 by sending 400 balista and 400 transporter.
Normally out of 3 attacks I will get 1 Wisdom Medals. Since I always attacking NPC level 5 for food, Currently I have over 200 of Wisdom Medal in my collection.
