The stronger your wizards become, the more likely they are to succeed in training.
Each round of training also has a random chance to reward one of the following:
Rewards can be claimed at any time after the round cooldown ends. Timing does not affect the rewards.
Wizards need to enroll (stake) before they can be trained. After a wizard is enrolled, it can be trained an unlimited number of times until it is unenrolled.
The GP cost is burnt, permanently removed from circulating supply.
Each round has a small chance of the wizard (temporarily) dying and being sent to the graveyard.
