Ant man relic

Ant man relic's rune state if a power sting is applied to the defender, inflict a taunt debuff reducing attack rate by 4%
But it does not state that it increases the chance of activating special attacks.
So it does increases the chance or just lowering attack rate.

This is something I’ve wondered too. I think it’s just the attack though cause I’ve had it last it’s full duration without opponents throwing a special.
