Can you go more indepth about the upgrade system? I really hope is isn't that bland typical upgrade system that 99% of servers use. It would be rather disappointing to see.
These items are obtainable only from creatures, so all creatures have a chance to drop these "upgraded" items. It isn't like the typical server where you use an item and the item is upgraded. I know I mentioned the upgrading item, but that is still in consideration and may not be used.
Basically it makes it so you can loot "better" loot from creatures. I'll give you an example.
This is a normal ice rapier:
15:09 You see an ice rapier (Atk:42 physical + 18 ice, Def:1).
It weighs 15.00 oz.
A deadly but fragile weapon.
This is a "rare" ice rapier, dropped by a demon:
15:09 You see an rare ice rapier (Atk:46 physical + 18 ice, Def:1).
It weighs 15.00 oz.
A deadly but fragile weapon.
This is a "mythical" ice rapier, dropped by a demon:
15:10 You see an mythical ice rapier (Atk:52 physical + 18 ice, Def:1).
It weighs 15.00 oz.
A deadly but fragile weapon.
The rare item is the second tier of the dropping system and not so difficult to loot. However, a mythical item is a much more rare drop and therefore more valuable. It is mostly applicable to bosses. Dropping one of VoltageOT's rare sets from a boss with a tier boost will yield much better performance then a regular drop. This is also great for new players, as they can get general items such as DSM or golden legs with a nice little boost.
Hopefully that explains it, if you have any questions feel free to ask.
