Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
alright so heres my build
up to the ionain boots the build is the same every time
if your enemy's have a heavy ap with massive aoe's team then take an abysmal scepter and a reverie
if the enemy is a heavy ap team with alot of nukes keep the scepter and get a banshee's
if they are a balanced team get a scepter and a hourglass
if they are balanced and you team cant seem to kill anyone get a legion and a reverie
if they are heavy ad get a hourglass and a legion
remember your ment to be the best support to your team possible.
get armor/resists based on the game at hand and always shield your ad carry or your ap carry if hes dying
remember when your playing janna your playing to HELP YOUR TEAMMATE SURVIVE!
