Not sure if this has been posted before (from searching I have not been able to find it).
Avarice blade is obviously a good item for gangplank, it basically looks like it was made for him. How many people know however that a static shiv proc from 'Parrrley' will apply the gold gain bonus?
This means that if if a single 'Parrrley' results in 3 minion kills from the static shiv he will gain an extra 24 gold (at rank 5). Hope this helps and abuse it to no end as the extra gold does help.
