Why ancient coin is better than relic sheild on Taric
As a level 6 Taric main it hurts to see people going with relic shield that doesnt really give Taric anything big other than some health a heal and a shield (or some wards) both he doesnt need since he already has one of each in his kit that are fairly powerful. Ancient coin on the other hand allows him to use his abilities without running out of mana to soon (with the help of mana Regen runes) which is why his early game is so fragile to poke and extended zoning offensively and defensively this build allows him to keep up even if his adc has 20 fps in both situations.Talisman on the other hand gives him much needed armor, a burst of movement speed (40% AOE) allowing him to do engages and force flashes really easily while bringing his team with him, and extra gold to build health items like Ruby sight stone which reduces cool downs on items by 20% and gives wards and needed health for only 1600 gold attainable with the extra gold from ancient coin into talisman, the talisman also gives Alot of cdr which synergies with Taric's passive thus his kit, which is all about counter engaging with his ult (or making plays) and peeling non stop and with the movement speed buffs on talisman, engaging. Using the extra gold from building talisman allows Taric to build ALOT of tankiness so he can peel up close and personal.
With this build It's Alot about late game and punishing over poorly positioned peeps early and late as well as hard zoning from the bushes. But most importantly being unstoppable peel late game because killing you will take too much effort and spells allowing you to do as you please. While your team backs you and crush those who dare try to pick you off. Your peel is also strong enough to 1v1 any squishy that doesn't build some defence. And even then can still chunk and cc really hard while always threatening to spin a team fight around with your ult, shields and heals. So in a nut shell the build path makes you stronger at all phases of the game and let's you not get blown up by the enemy team.
