Weapon and Armor forging.

Since the description says: "Collect the greatest weapons, forge your own unique armour, embark on your own journeys and realise your dreams as a Ninja!" I could give ideas for the forging.

I think it could be, that before someone can forge hes own unique armor, he needs to buy a common one at shops.
Later the player could either get a "forging material" as a drop from a mob (enemy NPC) or buy for some expensive price at a special shop.
There could be a common material, unique material, rare material and elite material. Common would increase armor stats barely, while elite would increase greatly.

Would it be good?

Yes, let's have a look at what you can make for us.

Well...

Common material could be Iron, with +5% stat increase. (Pretty Cheap)
Unique material could be Silver, with +15% stat increase. (Expensive)
Rare material could be Gold, with +30% stat increase. (Very Expensive)
Elite material could be Platinum, with +45% stat increase. (OMFG Expensive)

Ok, we need a money system to work out prices here though.

Btw, should we make "basic NPC enemies" ?

the ones, that will be used, when player will simply want to get exp by killing NPCs.

Yes, we need that for a MMORPG Forum RPG thing.

I'll make a list of them

Ok, then I'll make some fake accs for any we need.

I will make one NPC per every 2 levels.

(First Level 1, then Level 3, then Level 5 and so on)

ok
