i experienced this too... twice already... 1st an othell and second time was a yul. im thinking it has to do with hide skill since its the common thing to both classes...
maybe, just maybe... when an othell or yul use hide skill they left a 'clone' there? lol
dwarf ,69 luc - made 1st elmore cloak +7 with 25 scrolls, 2nd elmore cloak took 72 to make +7
ertheia, forgot luc, sure low - 73 scrolls to make +7 elmore
