Masters

Minions

Making the Bond
"Tap to select/unselect a familiar. Tap and hold to view the familiar's stats. First select the familiar that will become the master, then select its minions. It costs gold to make Blood Brothers. After the bond is made, the minion will no longer appear in your familiar list. Familiars in a brigade can be selected as masters, but not minions."Taken from in-game Help

Master Skill Levels
"Creating a Blood Brother gives Skill XP to the master, raising it's skill level. Higher-level skills proc more often during battle. If a familiar is at max skill level, it cannot be selected as a master, though it can still become a minion."Taken from in-game Help

Master XP
"Rare familiars earn more skill XP when selected as a master. Making Blood Brothers from two of the same familiars provides a further skill XP bonus."Taken from in-game Help
