Let me open by saying: No offense/challenge intended:
Why does Spiral ring beat at least one Terrasoul? With such a large modifier on VIT wouldn't it be better to stack that where possible? Or are you calculating that the STR modifies overall attack numbers more favorably after a certain point?
5 STR can give you 1 rank on Fstr, but with such a heavy VIT mod Terrasoul be equally or better then Spiral. Stacking VIT can give you a higher WSC and especially with the 100% mod it may impact Upheaval more then 1 rank in fSTR that Spiral Ring would give.
Terrasoul should pull ahead on Upheaval. The case in which spiral would be better is when you are using say Torcleaver on DRK.
Upheaval= 100% VIT mod I would say Terrasoul all the way.
Torcleaver= 60% VIT mod so gaining 5 STR[1 fSTR about] in the place of 2 VIT may benefit you slightly more.
On a weaponskill where the Mod isn't 100% FSTR can still be important. But VIT alone would directly increase the base DMG correct? With Upheaval's heavy VIT mod you may benefit more from the 2 VIT> the 5 STR.
I'm thinking stack VIT where you can. But the difference between a spiral ring and a pyrosoul ring would be small. Then again every little but adds up in the end.
Nightfyre or anyone else mind critiquing this for me here? I'm majoring in criminal justice, Math not so much.
