Moon-Lancer said:if you have a scyth, thats 4d10 on a crit, not to mention the normal damage.
In 3.0 their is a prc called deepwoodsniper. It adds crits to a bow. you can get a bow to do 5d10 and their are spells that can help you auto crit. Really the enhancement isent for everyone.
its not d10 per 'x' its 1d10 per 'x-1'
so a x2 weapon deals 1d10... x3 deals 2d10... x4 deals 3d10 (thats a scythe)
and a good deepwoodsniper deals +4d10 damage on a crit cause of the x5...
You're 1d10 off

the posible defening made by a thundering weapon isn't crucial to a monster.. i'dd much rather drop by wit my dwarven waraxe and deal +2d10...
