Items/Armor

Barbarian Armor
The Barbarian Armor was crafted by Erhard specifically for Naofumi with agility and defense in mind in preparation to his first wave of calamity. It is similar in defense as the Chain Mail he purchased on the first day he was summoned, but can also be upgraded. It is made of cheap copper and iron as well as Usapil and Porcupine hides, and a few PikyuPikyu feathers. The sleeve holes are lined with Usapil fur with a heavy-looking piece of metal covering the chest. Parts not covered with metal plating were lined with Porcupine skin. The interior was formed of two layers of skin and is lined with PikyuPikyu feathers. It is similar to the type of armor bandit lords would wear and has a wild vibe.

Barbarian Armor + 1
In preparation to the third wave, Naofumi asked Erhard for new weapons and armor. Erhard suggested using Chimera and dragon bones, covering the armor with dragon skin and then adding the Zombie Dragon's core to the center. Naofumi agreed to the upgrade, supplied the materials and paid the 5 gold fee.

This new armor is held together with dragon skin (which looks like a glossy black rubber) instead of a denim-like material. However, the overall look of the armor stayed the same. The armor is enchanted with self-recovery and several other functions

Barbarian Armor + 2 (Web Novel Only)
After the fierce battle with the Spirit Tortoise, Naofumi's armor was damaged beyond the armor's「Autonomous Repair」ability. Naofumi took it to Erhard for repairs. During the time it was being repaired, an incident occurred with Gaelion causing Naofumi to lose the core he was holding that used to be embedded within the Barbarian Armor + 1. After the said incident, Gaelion replaced the lost core with another that he somehow coughed up. The new core makes the armor lighter and gives a number of additional bonuses, however, the armor loses its「Darkness Resistance (High)」. Found in『Chapter 215』of the web novel.

Barbaroi Armor + 2 (Cursed)
After the fierce battle with Kyo and the Spirit Tortoise, Naofumi's Barbarian armor +1 was damaged beyond the armor's「Autonomous Repair」ability and ceased to function due to crossing from Raphtalia's World to Glass' World. Naofumi left it to Romina, the jewel blacksmith, to make a new armor based on it. it's made using materials from the 4 holy beasts. Romina also found a way to merge the Zombie Dragon's dragon core with one of the Demon Dragon's dragon core. The new core is bigger and gives a number of additional bonuses, however, the armor loses it's Darkness resistance effects. As soon as it's worn, the armor curses the wearer and damages them. However, Naofumi's defense was high enough to ignore the damage, making it feel somewhat tight in some spots.

Barbarian Armor + 3
After Naofumi returned from Glass' World with the Barbaroi Armor +2, the armor stopped function. He took it to Erhard, however this new piece stumped the blacksmith and Naofumi had to wear Magic Silver Armor in the meantime. With the help of his master, Erhard was finally able to use materials from the Spirit Tortoise and a dragon core that Gaelion had dropped off to upgrade the Barbarian Armor +2 (cursed). Overall, it looks similar to the previous Barboi armor but tortoiseshell colored material had been added to the metal parts and the color had been brightened up. It looked to Naofumi that Erhard had enhanced the pieces of Romina's work that had ceased to function when he traveled outside of Glass' World. The Q'ten Lo leadership paid for this armor upgrade. Later, when Naofumi crossed over to Glass' World for a second time, this armor only had a minor status decrease instead of a complete functional failure.

Penguin Kigurumi
The Penguin Kigurimi is a Penguin-resembling doll wearing a Santa Suit that is acquired through a Karma Penguin drop. Its purpose is the same as a suit of armor with some additional abilities and perks. It can conform to the user's size but will transform them into a penguin-like creature. Its capabilities are at least as good as Naofumi's Barbarian Armor +1. Rishia wore one to compensate for her lower level after joining Naofumi's party however she upgrades to the Filo Plush soon after. Also found in『Chapter 107』of the web novel.

Filo Kigurumi
The Filo Plush is a suit of armor similar to the Penguin Plush however its stats are far superior. This is a unique item made by Erhard using items and materials collected from Cal Mira Archipelago and inspired by Filo in her filolial queen form. This sleeping-bag-like kigurumi transforms the user into a filolial and even allows growth and status adjustments for filolials to be applied to the user. Rishia used this armour until she grew out of her kigurumi phase. This is also found in『Chapter 115』of the web novel.

Angel Breastplate and Filo Pajamas
Upon crossing over to Glass' World, some equipment including the Filo Kigurumi stopped functioning properly due to the two world's magic functioning different. Naofumi took the Filo Kigurumi to Romina in order for it to be upgraded to be compatible to Glass' World. Romina used the best parts of the remaining Kigurumi to create the Angel Breastplate. This pink breastplate was mainly pink with some gold and blue accents. According to Naofumi, it looked like a refined, high-quality pieces of craftsmanship. Apparently, creating this breastplate was harder than creating the Barbaroi Armor +2 since the material was "strange".

With the remainder of the materials, Romina created the Filo Pajamas. She was apparently embarrassed to have even created such a piece. Rishia ended up using the breastplate since she had the worst stats while Filo got the pajamas.

Prototype Raph Species Teakettle
Inspired by the Mt. Kachikachi fairy tale involving the Tanuki, Naofumi created a teakettle-like armor with Rat and Holn's help. This armor is to be exclusively used by the Raph species. The metal is made from Spirit Tortoise materials which provide great defense without losing mobility and it can generate steam to allow the Raph wearing it to float.

Mikey Armor
Using armor based off the properties of the slime monster Mikey, alchemists Holn and Rat were able to make single-use armor which could protect the wearer from attacks which inflict incurable wounds.
