Monster Raider Armor

The Monster Raider Armor set is composed of the Skeleton's Helmet, the Guardian Chestplate, the Creeper Pants, and the Tarantula Boots. This set is the upgraded form of the Monster Hunter Armor.

This is one of the "secret" sets, as none of the individual items show that they are part of it beforehand. When the set is complete, each item still has its ability. The difference between the Monster Raider Armor and the Monster Hunter Armor is that this one reduces 35% damage from mobs and does 35% more damage to mobs instead of the usual 25% with Monster Hunter Armor.

Trivia

 * This set is useful for Slayer bosses as it provides a damage boost to weapons while still surviving against monsters with the ability that causes the wearer to take less damage. It is possible to solo a  Tarantula Slayer with this set.
