Here's my idea... EX. Velocidrome Greatsword, you could make it with some ores and...idk... 4 Vel-Drome Claws and it would have a set amount of damage (you could see 4 claws). But with additional materials , like another claw (and you could see the additional claw, making it cooler), you could upgrade it and it would give it a small boost to attack, element, affinity, or slots. You could upgrade it more than once, and when you upgraded it fully you would get a medium-sized boost to attack, element, affinity, or slots.
If you like it can you put a point for like? Thanks!
