Crafted vs. Forged Items
First things first! Is crucial to understand in R.O.H.A.N., the distinction between crafted and forged items, because each type of item has a different enhancement path:
Crafted items can be upgraded through different tiers. Forged items, however, come in base/plain, rare, unique, and ancient levels, with each level built upon the one before. Notably, forged items are safe to reinforce up to level 5, while crafted items have always a chance of failure when trying to level up (the more level, the more chance).
Here's a quick summary:

Benefits of Enhancing your Equipment
Enhancing your equipment provides a straightforward way to increase your character's stats, such as attack power, defense, and other relevant stats!

(PVE) Efficiency: With higher stats, you can farm more quickly and with fewer resources, making your farming more efficient and cost-effective.
