Purple? Are you sure purple can go as high as 14 above 50%?, Personaly I havnt seen or heard of this. If true and req9-10 then probaly as much as the last gold 14>50% which was 2mil...maybe 1.5mil for this one.
well, this is a crystalline, making it a good sword...its just ppl arent really hexed that much making it not too interesting to no be getting dmg boost...often at least
