Adaptive Armor

Adaptive Armor is an Dungeon Armor set that can be obtained in Dungeons by killing The Professor and requires Catacombs Floor 3 completion to wear. Inside of dungeons, it is better than Superior Dragon Armor in almost every aspect when maxed while in dungeons, but it is an extremely rare drop. In addition, the Superior Dragon Armor costs about 40-50 million, while the Adaptive Armor Set costs only about 7-9 million and is better in Dungeons. It should be noted that Adaptive Armor is a Dungeon Item, which means its stats can get boosted while inside a Dungeon; however, outside of a Dungeon, the set is not nearly as good.

Note that the additional bonuses based on the selected dungeon class apply per armor piece.

Obtaining
Adaptive Armor is a rare drop from The Professor on Catacombs Floor 3. The Chestplate is much rarer than the other pieces.

The Adaptive Chestplate and Leggings can be also obtained by reaching the Boss Collection Milestones.

Sometimes in chests, the armor piece may also include high level Enchantments such as or  or may even be Recombobulated, making the drop even rarer and more valuable.

Trivia

 * Due to higher and  given, Shadow Assassin Armor is a much more effective set for people who are doing melee damage.
 * This armor (along with Adaptive Blade) are likely based from League Of Legends's (removed, old) Adaptive Armor mastery and Adaptive Helm item, although the stats/effects are not the same from this one.
