rarity ??? maybe. but usefulness, same as 40 and 50 leons. i would not buy it for more than 300 LGS. its my opinion.
and that item can be crafted.
to make a lvl 55 Leon weapon :
50Lv Leon’s weapon,
10 pcs of transparency Holy stone,
10 pcs of Herodian Gene Chip,
50 pcs of Talic Crystal,
200,000,000 of race money
Holystone: combine 99 Holystone pieces (drops from ore +1,+2,+3) you get 1 Holystone
Herodian Gene Chip: is a item wich is dropped by Dagnu PB in Elan
Talic Crystal: farm in elf land on metal elf mobs or combine 20 talics at hero for 1 talic crystal
