I bought GameMastery's critical hit and critical miss decks, but they aren't universally loved in my group. Perhaps it is for that reason that I started working on a critical hit chart that straddles the line between detail and efficiency. Well, that and the desire to incporporate the oft left out d30! Though it is still very much a work in progress I thought I'd share with you what I have so far.
Initially when scoring a critical hit one rolls a d8 with the following result in addition to the normal critical damage (x2, x3, etc)
1. Equipment Damage
2. Muscle Damage
3. Extra Damage (Minor)
4. Bodily Jarred
5. Extra Damage (Major)
6. Free Additional Attack
7. Bleed Damage
8. Broken Bones
Equipment damage includes things like damaging an opponents armor, shield, or even weapon. Muscle damage would result in penalties and reduced movement rates. Minor extra damage adds even more damage to a critical, typically a single die, while major extra damage adds two dice. Bodily Jarred includes things like losing a hold on weapon or shield, being knocked down, or knocked back, etc. Free additional attack allows for the person who scored the critical to make another attack at the same bonus as that which scored the critical. Bleed damage results in consistant loss of hp every round (see below). Broken bones produce a variety of effects from reduced movement speed to paralysis (see below).
In addition to the additional charts, muscle damage, bleed damage, and broken bones. First drafts for both Bleed Damage and Broken Bones can be found below.
That's all for now. I'll post more when I have an update, the next step will be the muscle damage chart.
