Aatrox has probably the worst tooltips up to date, with more missing than not.
Passive: Pressing shift adds the 2 Seconds CDR and the 40% Multilator Description, which is not alot and important enough for the main Tooltip.
1.%Damage increase on consecutive casts
2.%Damage increase on hitting with the blade edge
5. Recast lockout
1. MS increase
2. Health gain/stored per second
3. Invincible Duration
4. Root Duration during revive
Also pressing shift only adds some empty space.
I really hope these are wip tooltips.
