Skill Tutor
Skill Tutor is a new addition to Event Dungeons where each day will have a different Initiative Skill to Farm. This Dungeon costs 10 AP and can be ran 2x daily with 2x extra runs to Buy at the cost of 15 Runes each. The BOSS will be a guaranteed Drop and the minions have a low chance of dropping as well. Each stage consists of 3 Heroes and the final stage will have the BOSS and 2 other minions. Each drop will be the Elite version of the card and can only level up an advanced Initiative Skill (+). It is not required to level the card to feed to your selected Hero.
