Allows you to counter the next attack directed at you.
Can Counter 1-3 times before wearing.
Counters that activate as a result of Perfect Counter are guaranteed critical hits.
Perfect Counter can fail to counter any attacks, and has a chance of simply deactivating. This occurs when you "miss" the counter attack. At capped hit rate (95%), Perfect Counter has a 5% chance of failure. At 50% hit rate, it only has a 50% chance of success.
Perfect Counter sets your Counter to 100. Counter Rate = Counter * Hit Rate, thus Perfect Counter is highly dependent upon your accuracy.
Perfect Counter will counter a mob that used Perfect Dodge up to 3 times although the log will say you "missed". The difference is whether or not the animation shows a hit regardless of the 2 hour.
Perfect Counter is not affected by Footwork. The damage is still based off of the player's normal Hand-to-Hand damage.
