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.
So with this build, you are going all out tank with taric.
you do need to get a fair amount of creep kills in order to get the warmogs fairly early and make it effective.
some tank players might look at Rylai's Crystal Scepter and say its not a good item for a tank. Well for most tanks its not, but it does really help taric. not only does it give you health, but it gives you like 60 ability power or something like that. THIS is really going to help your Ult to heal you in team fights. and if you wanted you could sub out Soul Shrowd for anther HP/Ap item, like Banshee's Vail. and since the Vail gives you like 400 health anyway, you will still have almost 5000 hp.
So for laning, you should get heal first. most people get stun, because we all want to get the gank and firstblood, BUT if you do this, and something goes wrong, you die. with the heal, you can keep you and your partner alive much longer and wear the emeny down.
And for fighting champs, just stun, run up to them, and shatter. at lvl 9 when your shatter is at lvl 3 or 4, you will hit them for 200-300 hp, which is still quite a hit at that lvl.
