Regeneration (3.0!)

[Mustrum_Ridcully]

What about burning individual parts of the troll? would it be possibly to burn small parts of it, so that eventually it dies becuase of the burnt parts inability to regenerate?

Yes, consider it as a coup-de-grace. With the trolls good Fortitude Save, it isn`t that easy, but certainly possible.

I guess you can only sever the head of someone under the following circumstances:
o You roll a confirmed critical with a Vorpal Weapon.
o You make a coup-de-grace
o you deal enough real hp damage that the target is at -10 or less and dies.

Even the DMG optional rules for called shots do not allow to sever any body part, just to cause penalties...
