Please try out my build and vote/comment. I'll continue work on improving this guide so it'll be more in-depth and easy to read.

First off, I don't claim to be pro in any way. I am simply a guy that likes to play League of Legends and Taric is my favorite champ. I choose to build him to be an aura support, bolstering your teammates and turning teamfights in your favor. This build makes him very well balanced in terms of stats, helping you to be well rounded and a good fit for most situations in-game.

I chose runes that would help cover Taric's needs and it helps him to be more effective and efficient in the lane:

Greater Mark of Alacrity: a little bit of attack speed so that you can utilize your passive and keep your mana pool up

Greater Seal of Clarity: mana regen so that you can continually heal/stun/shatter/etc.

Greater Glyph of Shielding: round out your defense with some magic resistance, protect yourself a bit from those AP users

Greater Quintessence of Potency: some AP to improve your healing and spell damage

3/6/21

Offense: AP because you won't get much AP from items
Defense: Not much in terms of defense, but every little bit counts (especially early game)
Utility: Most champs benefit a lot from utility, Taric is no exception. It's also good to pick up the masteries for your summoner spells.

Start off with Doran's Ring, getting that extra HP, mana regen, and AP. You should be able to stay in lane until you have enough for Philosopher's Stone. Continue to stay in your lane stunning and healing until you get to 1200 G, then it's a good time to go pick up Mercury's Treads. About this time you'll be getting towards your mid-game teamfighting, which is good because you're ready to start building aura items. The most staple aura item is Aegis of the Legion, boosting defense may not seem super exciting but your team will be glad that you did. Now you can build Shurelya's Reverie (thankfully you'll already have Philosopher's Stone), and this is one of my favorite items because of it's active. Afterwards I recommend getting either Stark's Fervor or Abyssal Scepter. Both are very good items, but it depends on who your allies are. AD champs benefit from Stark's Fervor and AP champs benefit from Abyssal Scepter, so choose accordingly. It's rare that you'll ever be able to finish the build, but I sometimes grab Soul Shroud for some extra HP and cooldown reduction.

I choose to max out Shatter first to make it's armor buff and damage output stronger. Be sure to drop a point in Imbue at lvl 5 to bolster your heals.

Then max out Imbue.

And Dazzle last. This is because it's best function is the stun, and you only need 1 point to utilize it, so leveling can wait for it.

As far as the new ult goes, I'm still trying to get used to it but I think that it's going to work well for aura Taric. Compared to his old ult, the new Radiance gives a massive aura buff of AD AND AP. Now your whole team can benefit from your presence and obliterate anyone unlucky enough to get caught in your swarm.

So before I was able to buy tier 3 runes (lvl 20), I was having some mana problems. Also, the opposition was really not extremely coordinated enough for me to need Clairvoyance to support my team.

So I think it's a good idea to use Clarity while your still in lower levels or if you're not used to using Taric yet. Having Clarity available let's you stay active with heals and stuns and not worry about exhausting your mana. It's also nice for sustaining a team fight when you're allies are running low on mana.

However, once you have enough mana regen from your masteries and runes, you don't need Clarity anymore and it's time to start using Clairvoyance. This spell should be on the support champ, which means you, and be used regularly throughout the match to help your team know where opponents are. You'd be surprised how many times you save your allies from a gank by anticipating their route and revealing their position.

Your second spell should be for mobility, so either choose Ghost or Flash. My preference is Ghost because it does a good job in chasing down, retreating, and getting to a teamfight ASAP. Used in conjunction with Shurelya's Reverie gives you an almost comical speed. I like Flash too, but for Taric I prefer Ghost.

Playing as aura Taric, you are invaluable in teamfights. With your own build and auras, you make your entire team more powerful and well-rounded. Be sure to be a good support and be vigilant in protecting your teammates, healing them, and saving them when they're being chased. You won't get a thank you from anyone, but you'll be smiling to yourself when their nexus explodes and this word fills your screen:

VICTORY

Thanks for reading, I hope this build has been helpful for you. ^_^
