Every day you can complete various quests: mandatory ones, necessary for completing the daily quest "Today’s Quests", and optional ones, which are at the player's discretion.
Complete the "Today’s Quests" five times to accomplish the "Path of the True" quest. 

Rewards for completing the quest:
Gold and Armory Tokens;
10 Rougarou shards (if you have less than 325 shards of this hero).
If Rougarou is already upgraded to 7 yellow stars, Power Stones are given for upgrading other heroes.

After completing, the quest counter resets, and you can start the quest again the next day.
