Vitality Points and Weapon Selection

[vinom]

I've been drafted into a game using the vitality point system, and I'm slightly confused on how to calculated the modified crit range on weapons with a range greater than just 20 if the multiplier is greater than X2.

From what I've read, critting is key as long as you're not fighting undead or constructs, and even then it over comes all damage reduction, even epic, so selecting a crit happy weapon in this no magic campaign will be crucial.

Basically you just add  the excess (greater than ×2) multiplier to the original crit range. I'm not aware of any such weapon, but if you had a 19-20/×3 weapon it would have a modified crit range of 2+1=3 so 18-20 (or one greater than originally). A hypothetical 18-20/×4 weapon would have a modified crit range of 3+2=5 so 16-20 (or two greater than originally).

Do you think you can get kaorti resin allowed?  A kaorti resin falchion is 18-20/*4 normally, so it would be 15-20 with this variant.  With keen, that becomes 9-20.
