Well, If all you have is around 60 stamina then thats the perfect weapon for you, otherwise, the 40 ssi is an absolute waste on any weapon that swings under 2.25 natuarally. The 50 DI isnt spectacular, and the 20something lightning is EH. You want something with Some Hit Lower Defense, Hit mana leech, Hit Spell(most folk like fireball or lightning) moderate SSI(depending on stamina) and some DI.
Try to find Kryss and Warfork combos that work well for you. lots of folk will use these fast weapons with a high SSI so they can keep there dexterity and stamina pretty low and jack there mana way up for specials and poisoning and such, hope Ive helped.
You have any slower weapons youll want more SSI
Here, If you got a kryss that looks like this keep it
50 Hit Lower Defense
50+ Hit Mana Leach
50 Hit Fireball
30 SSI(not really neccessary IMO)
and anything over 40 DI
This is pretty high end though and your probobly not going to find this combination of mods this high on your weapons but if ya do awesome
