since this is a tanky build it depends on what your against but this is the build that i seem to use the most.... if u have alot of ad attacking u get thorn mail instead or force of nature.

if u havent played voli yet the more hp u have the more your Frenzy hits for so even though u have a very tanky build u can still rock enemies.

his ult and slow get bonus damage from AP so if u are gonna change parts of your build its a good idea to get AP items with HP like Rod Of Ages. i mainly go with Rylai's cause when u pop your ult in team fights u will be slowing there whole team.

Voli is a beast of a tanky dps but u have to remember just like other champions wait for your moment to strike ... like tossing them into your turret ;)
