Magic tools

There are many types of tools. While details are vague, it has been safely established that Magic Tools are crafted from monster parts, Soul Cores, Skin/scales and bones etc... 
As there are Monster levels, there is also varying quality of magic tools which depends on the monster level the material comes from and the skill level of the crafter. Naturally the higher the monster level, the more complete the material/parts and the higher the crafter's skill, the more likely you get a better quality item.
For example, an armor built from a Warrior Level monster skin will be able to let the wearer shrug off Novice Magic but will have less effectiveness against Mid-Tier Magic which can sometimes obliterate the armor's defenses in one blow!
Lightning Element spells can negate even more from magic items' defenses. 
While many people value the use of Magic equipment, the protagonist rarely uses any because his rate of growth far exceeds what any standard equipment at his level can handle.
