Idea for a Karma Rework

Just an idea so her gameplay has more of the Karma theme.

Passive (Karma):

If Karma receives a heal/shield or any other buff, then Karma´s shields and heals are stronger for this ally. Last for 1 minute with a 30 seconds cooldown for this ally. The strength of the heal/shield buff (Karma) is dependent on the strength of the buff she receives. If she received a base stat buff, then her heals/shields are 2.5% stronger; if she get a shield, then her heals/shields are 5% stronger; if she receives a heal, then her heals/shields are 7.5% stronger. If allies use the passive, then it gets stronger -> +0.5% for one usage (up to 3 times/ 1.5%: 2.5->4%;5%->6.5%;7.5%->9%)(only for the ally who used the passive).

If Karma receives any damage or debuff from an enemy, then her abilities have additional effects for this enemy and she deals more damage per autoattack to this enemy. Lasts for 30 seconds with a 15 second cooldown. The effects are stronger if enemies had this passive already (stacking up to 3 times).

Q (Inner flame): Karma sends forth a ball of spirit energy that explodes and deals x magic damage upon hitting an enemy unit. Passiv (Karma): If the ball of spirit hits an enemy with the passive on, then a cataclysm gets created which deals x magic damage after a short delay.

W: Marks an ally/herself or an enemy.

Ally: The mark activates itself, if the ally gets 3 times damage from enemies. The mark heals the ally for 25% of the highest damage taken (from those 3 damage parts).

Enemies: The mark activates itself, if the enemy deals 3 times damage to the first champion, which he dealt damage to after receiving the mark. The mark deals x magic damage. The mark also activates itself, if the enemy kills the allied champion with one autoattack/skill, while the allied champion had 1000 or more health points. Passive (Karma): If the passive was activated, then she deals additional x damage to this enemy. This effect can only be used once per usage of the passive.

E: Karma gives herself or an ally a shield. Passive: If an enemy deals damage to the shield, then allies in x range also get a shield. Passive (Karma): If an enemy with the passive deals damage to the shield, then the shield explode after x seconds dealing x magic damage to all enemies in x range.

R: Karma says a curse, which let all damage and debuffs affect their provenance (-> If an allied/enemy Sejuani uses her ultimate and hit an enemy with it, then she also gets the slow/stun and the damage). Karma cast the spell for 2.5 seconds and is rooted while she cast it. The screen of every player is blurred golden. The spell lasts for 5 seconds.
