Air Slash = AS/ 30% Flinch Rate
Serene Grace = SC/ Doubles (*2) added effects
King's Rock = KC/ 10% boost
Flich Rate = FR
Formula:
(AS x SC) x KC= FR
(30 x 2)= 60 (Air Slash with the Serene Grace boost)
60 x .10 = 6 (King's Rock boost)
60 + 6 = 66 (Air Slash with the Serene Grace boost + King's Rock boost)
New Flinch Rate is 66%
