Kassadin Nether Blading Towers
When Kassadin auto-attacks a tower, his Nether Blade passive applies to it, dealing ~40 magic damage on top of the 0.5 bonus AP ratio from attacking towers. This (as far as I know) is entirely functional.
When Kassadin activates Nether Blade and attacks a tower, it doesn't apply the passive - which is intended - but it also doesn't apply the damage from the passive.
Steps for reproduction:
- Pick Kassadin.
- Attack a tower.
- Activate Nether Blade, and attack a tower.
