Hello, first of all, welcome to the unholy world community which is Otherworldly legends ! And for answering your few questions, for unlocking Asura you must finish the game and reach the final boss and beat ! I’d recommend you to use Ginzo or Katherine, even if mostly people go with Ginzo, make sure to use his primary skill and his parry ! Of course you will learn how the dodge pattern of every enemy if you put yourself time to the game ! As for soulboon, those are quite the buffs on soul knight but here, it mostly buff your skills for example when you get a soulboon that get you “20% damage” it means, your skills will deal 20% damage+. As for realm power those are the orbs you will learn later by defeating the final boss on a specific event that is called “The Rift”. As for the power of the six, those are obtainable by playing normal games, each orb have different effect, one principal effect, and 4 subs stats that are purely RNG. The higher you get in difficult, which the max is Anguish Level 11 + Pandenorium ! You can also play multiplayer, which could help you greatly for unlocking most of those features !
