Since it is 2hand you are effectively losing one slot where you could wield another nice item. Therefore the stats should be devided by 2. Then it comes out as:
AC: 18
STR: +15 DEX: +18 STA: +15 WIS: +18
HP: +100 MANA: +113 SV COLD: +15 SV MAGIC: +15
SV POISON: +15
Recommended level of 31 (j/k)
It would still be a very decent 1hand item, but I would say it is about the average primary/secondary one can expect from guys who play the high end game on this level
