Dark Souls II - 38 Lud & Zallen, the King's Pets perfect battle

You liked Aava, right? You did, didn't you? Yeah? Good! Here's TWO OF THEM!
Lud & Zallen have the same attacks Aava has. The difference is that they make your weapon's durability degrade faster, so having repair powder with you is a good idea. The seconds cat doesn't enter the fight right away, it only does when the first one's HP goes below certain point. After one cat is dead and the remaining one's HP is around 1/4, it will go into a super mode, which regenerates its HP and increases ATK and DEF. It lasts for about a minute, so no need to be extra aggressive.
