How do I use Orbs of Eltar?
Orbs become available to players Level 3 and higher. Your balance of Orbs by type can be seen by tapping the Blue Orb icon at the top right of your screen once you reach the appropriate level.
To use these Orbs to level your characters abilities, open your Team Roster then tap Info on the desired Warrior. Abilities that can be leveled will show a leveling bar under them. Tap on these abilities for information about how to increase the effectiveness of that ability.
