http://lineage.pmfun.com/?s=+Hour+Expiration+Period&x=0&y=0
thats are part of the christmas event...
but, i think that can works too in the "shadow boss" jewels that you can buy from olympiad manager (30 days jewels with same of some boss jewels)
but.... in my server is alrredy fixed
nicee works for me too
and works too when you have 2 subs for example 1 sub lv75 and other lv 61.. go and change to one sub, an then the oter less level
and you can use S grade equipment with sub lv61
in all the l2off that i played the game ron much better than in the l2j, but the bugs are there too, not too many, i guess because the l2off that i played are always in a old chronicles.
l2j are in the latests chonicles, but some bugs are from the firsts ones
