Wither Armor

The Wither Armor is a Dungeon Armor set that can be obtained from post-boss chests in The Catacombs - Floor VII. It gives the same stats as Necromancer Lord Armor (Besides the Helmet, which has 60 less Defense but 15 extra Intelligence.) except with a 40% damage reduction against withers. However, it can be upgraded using Precursor Relics to make some of the strongest armor sets in the game for Speed, Damage, Intelligence, and Effective Health. Like other dungeon armor sets, the chestplate costs the most of all the pieces. Note that the full set bonus does not work unless all four pieces are of the same variant.

Essence Crafting
Wither Armor can be upgraded into Storm's, Goldor's, Maxor's, or Necron's Armor by surrounding any piece with any 8 of the same Precursor Relics: L.A.S.R.'s eye, Jolly Pink Rock, Bigfoot's Lasso, and Diamante's Handle. Upgrading the armor will keep all existing stars, reforges, and enchantments. Variants of Wither Armor can also convert between each other using the appropriate Precursor Relic. For instance, a Necron's Chestplate can be converted into a Storm's Chestplate with 8 L.A.S.R. eyes.

Tips

 * Players usually use 3/4 of the upgraded armor sets paired with a stand-alone helmet (Tarantula Helmet, Mender Fedora, Shadow Goggles, Trophy Heads, etc). This is sometimes better than using the full set.
