Lunox

In the laning phase, use Lunox's 3rd Skill to slow the opponent and her 2nd Skill to poke. When she takes damage, use her 1st Skill to heal back up.

In teamfights, use Lunox's 3rd Skill to slow enemies first and follow up with her 2nd Skill to gain the Power of Chaos, then activate her Darkening Ultimate and spam her 2nd Skill for a lot of damage. Afterwards, use her 1st Skill to gain the Power of Order, then activate her Brilliance Ultimate to become invincible and deal damage to nearby enemies.
