the combination of Air Slash and Serene Grace allows Togekiss to fence

off many foes, posing a decent offensive presence. With Air Slash's

increased 60% flinch rate paired with paralysis, the opposing Pokemon

is left with just a 30% chance of successfully moving.

So its 30 Percent change w/o the rock

All moves that actively deal damage and do not already have a chance

to flinch will gain a 10% chance of flinching the opponent. (This

chance doubles to 20% if the holder has Serene Grace.)

So kings rock will not help

30% :2 (flash) = 15% Percent chance of attacking
