Alternate Taric Ult concept.
Cosmic Radiance -> Crystal Radiance 90/80/70 second cooldown.
Taric crystallizes all allied units, and allied turrets; in his area. Those effected are crystallized for 3/4/5 seconds. Crystallized units gain 100/150/200% of Bastion's bonus armor and Taric can cast off of all allies effected and deal 5/10/15 ( 20% Bonus Armor ) magic damage with attacks and abilities. *You cannot do more damage or heal more than normal with these abilities.
Breakdown:
Taric empowers people and give them a defense steroid for a short time. During that time allies will deal bonus damage based on their armor and all count as Bastion linked targets. This includes minions, pets, summons and even turrets.
Yes, Rammus will be OP when affected by this.
