I checked out Arms & Armor which had AC Values and %s and then the Castle Keepers Guide for ideas. So far this is what I have.
My idea is to have everyone roll a d8 and d20 at the same time. If a head is hit with no helmet, then it will be an Automatic Critical. Thoughts on this? Anyone else use Helmets in game or hit location?Castle Keepers Guide, Page 257 wrote:Randomly Landed Blows
Most attacks against a foe do not strike exactly where the attacker intended. Sometimes aimed at a chink in the opponent’s defenses, a strike misfires due to the opponent’s own movements or other battlefield conditions. These blows strike in seemingly random places. To determine where a such a blow strikes it is a simple matter to assign a number to a body segment, and then roll a related die for the purpose of hit location.
Table 17.7A Randomly Landed Blows: Humanoid Target (Human, Elf, Dwarf, Goblin, Kobold, Giant, Ogre, etc.) Roll 1d8
1. Head
2. Left Arm
3. Right Arm
4 - 6. Torso
7. Left Leg
8. Right Leg
Last thing, I always add the Monster hit-dice to the attack roll, except for 1 HD monsters. But what about Damage - do any of you add their HD to damage? Thanks.
