Leona's Passive

I feel like Leona's passive should have a ratio, so yeah, there you go:

Leona marks enemies with Sunlight for 4 seconds each time she damages them with an ability. Allied champions consume Sunlight on enemies they damage, dealing 1-7% of Leona's Maximum Health (based on ultimate level: +2% per level) bonus magic damage. Can only be applied every 2 seconds per enemy champion Also your ultimate procs your passive on champions stunned but only marks enemies slowed
