Critical damage with weapons

[Lumikettu]

Kinda dumb question, what all are added to critical dmg? For example if one were to use +1d8 19-20/x2 +1 ench +1d6 fire longsword with 14 str, +2 dmg. What all would be rolled again for critical dmg?

A critical with such a weapon would result in the following damage rolls

2x 1d8+3
1x 1d6 fire

When you crit, you roll the weapon damage dice several times and multiply all bonuses to damage, except those that are written as not multiplied on a crit, like precision damage (example : sneak attack) or weapon special property (like flaming).

With a +2 Strength modifier and a 1d8 19-20x2 +1 flaming weapon, the crit would be :

2d8 + 2(2(str)+1(mag)) + 1d6 = 2d8 + 6 + 1d6

Let's say you are level 3 and used power attack :

2d8 + 2(2(str)+1(mag)+2(PA)) + 1d6 = 2d8 + 10 + 1d6

To clarify why rocky's math is spot on in a nutshell you always roll multiple weapon dice, multiply all static bonuses, and never multiply bonus dice.
