If you are wanting to farm with the Character do NOT Use Dazzle for minion kills, At level 6 shatter will almost kill minions and you'll have your berserker Greaves for extra attack speed, This will help you pick up minion kills fast. Your minion kills should be the highest out of the whole game i usally end a game with about 500-600 minion kills (:

Heal is because Imbune dosen't come intil later levels, So take heal to heal your self up, ignite if needed to dazzle, Shatter and then ignite and run away , Then take a heal as you're running away from the other champion on your lane. This should almost guarentee a kill if the champion you Dazzled and then Shattered was low enough health, You can also basic attack the life down at later levels.

Been as the Taric AD Build is more complex than any normal off-tank or on-tank builds for Taric you must always keep your Dazzle and Shatter up so you can deal a maximum damage to your opponents plus having these at level 5 at earlier play also makes you more efficient to get fed in earlier game. later game is where the team fighting comes in where you should of then had imbue to help/save your team mates.

You're building AD.
The madred's razors help you deal extra damage to tanks as you're constantly hitting from this item.
The sunfire cape allows faster minion kills and more efficient when also taking down tanks or other enemy champions as your damage is constant.
Same with the wit's end 42 magic damage is constantly beinng hit on tanks or your other champion on the opposit side, So it's all great.

As you get a big bonus from Madred's razors in attack damage you don't get that much from it to make it a AD Build the Atma's impaler gives you 2% of your max health into AD So that makes taric more efficient

The pros of this build. Taking down tanks and enemy champions is EASY!
The cons at later game when the other champions are all at level 18 you're almost like a full AD Champions with not much Armour wich is what Taric is used for , So keep a look at for health drop.
