Armour, weapon & equipment damage

[Aus_Snow]

What d20 rules exist for cumulative (realistic) damage to armour, weapons and other items, and where can they be found?

Also, how accurate and/or usable are these various rules, according to your experiences?


I'm only familiar with a couple of sources for these kinds of rules, but I imagine there are quite a few.

Last of all, who continues to use such rules?

There are the Hardness/HP rules in the PHB & DMG, of course, but they basically assume that each hit is in a different location, so if you don't sever the item in one blow, you start again from scratch, on the next attack.

I used a custom made ruleset for this along the following lines:

Armor has HP (adjusted for material) on a basis of 10HP per armor class point protection offered. Everythime someone is hit based on flat footed AC (i.e. the blow is caught by the armor), the armor receives damage. Once 0 HP is reached, the protection factor is lowered by 1 point, and there is a 'new' HP total based on that AC...

F.ex. Chain Mail, 5 steps AC protection, has 50 HP. A PC with 2 points dex bonus to AC, but nothing else, is attacked. The attack roll would hit AC 8 (was under old 2nd Ed rules), thus the armor is hit and takes damage. Once 50HP total damage are done, the Chain Mail is damaged and now offers 4 steps AC protection, and has 40HP before suffering a further setback. Once the AC protection reaches 0, the armor is completely beyond repair.

I used this only in situations where the PC's were in an environment where repair or the purchase of new armor is difficult (i.e. stranded on a lost continent etc.), otherwise it is fairly cumbersome...
