Crusher

A larger step up to the Blade Master in comparison to how these monsters were in regards to the Armor Guards, the Crushers have gained an additional immunity to Sickness, and while their main attack has been downgraded to Double Slash, it's made up with the fact that they have access to two new skills: the first one is called Smashdown, in which they hit a party member a single time, causing Seal if it connects and it isn't blocked perfectly; and the second is Grand Tornado, in which they conjure a whirlwind that hits all party members four times. The first attack is rather easy to block, but it still shouldn't be disregarded, as getting a party member Sealed will reduce their effectiveness in battle greatly due to leaving them unable to use anything but Lv. 1 attacks, while Grand Tornado is hard to block due to its hit number and multiple targeting, so this is an enemy that shouldn't be understimated.
