Battle Trance Mastery
Grants up to 3% increased damage over 3 seconds when in combat with enemy champions
Does that mean if i do 100 damage on basic attack i do additional 3 damage on each basic attack or enemies take 3 damage over 3 seconds which makes it 1 damage per second
So the damage is increased by 1% each second you are in fight with enemy champions up to 3%?
