i checked the stats of some sos swords and its not much better damage than the regular swords if i wait 2 levels that i would have the same damage, is there something im missing about sos items that make them way better?

yeah the +

whats the + mean?

the + mean 1 lvl higher ( which mean better stats ) ... so a wep lvl 16+8 will be same as 24+0

plain sos = +5

plain som = +10

plain sosun = +15

so if you have a sos wep lvl 24 +5 wich mean 24+5+5 = wep 32 +2 = stats of a wep lvl 34

more is + better is the wep ...

vouch totally correct^^
