While Yao Guang holds "Certified Banger": After an ally target uses an attack, triggers the "Great Boon" effect, dealing 1 additional instance of 10% Elation damage of the corresponding Type to 1 random hit target. If this attack consumes Skill Points, then additionally triggers "Great Boon" 1 time. When triggering the "Great Boon" effect, if the attacker's Elation is lower than that of Yao Guang, then this instance of Elation damage will take Yao Guang's Elation into calculation. Triggering the "Great Boon" effect is not considered as using 1 instance of attack.
