Тему в топку.Runic Power is created when the Death Knight uses an ability that requires a rune/s. If the ability requires 1 rune 10 RP is generated, 2 or 3 runes generated 15 RP. There are many talents that allow the Death Knight to generate additional RP by casting a specific ability or avoiding a blow. Anti-Magic Shell also generated RP when it absorbs damage. It goes for rough 1 RP every 100 damage.
