Gangplank Q-Parley, is an ability, but is treated as an auto attack, where it is affected by things like: Ninja Tabi's passive- reduces parley's damage by 10%, Pantheon- passive blocks parley, teemo's blind, cause parley to miss.
First off how does ninja tabi counter one champ sooo hard.
Lets just say:
Im running armor pen reds and quints, im doing decent amounts of damage(like 80~120 dmg at lvl 6, he/she goes back and buys ninja tabi, its now lvl 7 and parley does a lil more dmg,
and i do like 60 dmg.
