In the end, Leon didn't manage to create the armor he wanted. As expected, creating an inorganic object that could drain, store, and restore his mana was a bit too much... However, Leon managed to make some interesting gear.
Semi-Indestructible Mithril Armor
It grants you: Endurance + 1500, Mentality + 1500
Self-Repair function: It uses the mana of the user to repair itself.
Condition: When the armor suffers any damage.
Durability: 18000 days
It was pretty impressive, but considering that Leon could use Mana Armor, Mana Shield, and Mana Barrier, it felt somewhat useless. However, Leon already met individuals that could ignore his defensive spells, so such armor was a necessity. Leon's ultimate goal was to create a power-suit, but it would take some time before that happens.
