I wouldn’t be surprised to see more skills added.
In DragonSoul, Orange Skills - otherwise known as “Legendaries” - were a way of making older/unused heroes more relevent. For this reason, Legendaries weren’t immediately available for every hero. Only ~3-4 per update. TBH, i could see the merit of this system, but i was not a fan. To this day, not all heroes have Legendaries & that game already has the next 2 promotion levels!
Aside from introducing new skillsets, another aspect of Legendary Skills that I liked was the fact that they introduced prerequisites for unlocking them. Unlike previous promotional skills - where all you had to do was get to that promotion color - Legendary Skills included 3 Quests as an additional requirement. This included:
- Sacrificing an item/gold for X days
- Checking in for X days
- Winning CW battles with specific heroes X times
- Healing/Dodging/Using a skill X times in 1 day
- And, more.
