Ber recently leaked modifiers/attributes coming to Vesteria. These are buffs that give weapons an extra boost like +10 INT, STR, etc.
(Attributes would be called things like Keen, Agile, Violent, etc)
I propose for these attributes to work similarly to how they do in Terraria.
Meaning that when dropped/bought, they can have positive or negative effects like + or -10 INT. Although, they can be reforged, maybe at the blacksmith. In order to obtain a new attribute. Price would vary depending on the weapons rarity/power.
