Mantra bonus: Inner Flame deals bonus magic damage and leaves a 250-radius AoE that slows enemies inside by 50%. After 1.5 seconds the area detonates, dealing magic damage to enemies inside. If Inner Flame does not strike a target, the area is created at maximum range.
Active: Karma forms a 650-range tether to target enemy champion, revealing and dealing magic damage to the target over 2 seconds at 0.66-second intervals. Gathering Fire is applied every time this ability damages. If the tether is not broken after the 2 seconds, the target is rooted for a short time.
Active: Karma shields a target ally for 4 seconds and grants the target bonus movement speed for 1.5 seconds.
Shield: 80 / 120 / 160 / 200 / 240 (+ 50% AP)
Bonus Movement Speed: 40 / 45 / 50 / 55 / 60%
Mantra bonus: The shield overflows with energy, granting ally champions within 700 range of the target half the shield value and 60% bonus movement speed for 1.5 seconds, while dealing magic damage to enemies within 600 range of the target.
Defiance scales with ranks in Mantra.
Magic damage: 60 / 140 / 220 / 300 (+ 60% AP)
Cooldown: 45 / 42 / 39 / 36
Active: Karma empowers her next ability cast within the next 8 seconds, adding an additional effect. Empowered abilities share the same cooldown as their basic form.
Karma begins with one rank in Mantra and can increase it at levels 6, 11, and 16.
Ranks in Mantra improve the additional effects of empowered abilities.
Mantra's bonus effects on abilities will stack on top of her abilities' normal effect.
Activating Mantra does not cause Karma's abilities to become available. Karma's empowered abilities share the same cooldown as her regular abilities. She cannot "double up" (like Rengar). 
Karma'sDefiance does not increase the shield value of her original target, but still grants the 60% bonus movement speed. The lack of bonus shield is speculated to be a bug.
