Flame weapons and their effects

By Malachai, in Dark Heresy Rules Questions

Currently within my gaming group the matter of what flame weapons do is of some dispute.

When it gets right down to it, i want to know if flame attacks ignore armor?

The primary reason for this being the metallic trait listed in the dark heresy book allowing one to use their armor value against flame attacks.

So what do you think?

maybe you can use the armor against the damage done if you catch fire.

against the first blow you have armor or i can't explain why the heavy flamer has a pen value.

That's how I've seen it. I apply full TB+AP against Flame attacks for the attack proper, and only TB for any continuing fire for those who fail their subsequent Ag check and light up. Otherwise having a Pen value for Flame-quality weapons wouldn't make much sense.

Likewise, the fact Machine trait allows you to use that machine armour against flame weapons leads me to believe regular armour wouldn't work against being on fire.

Precisely. There's the first attack from the weapon and there's the continous damage from standing ablaze. Armour helps against the first one.

Quite right.

Page 210: Special Damage ; Fire - "Once you are ablaze you take 1d10 Wounds (with no reduction for armor) and 1 level of fatigue each Round until you are extinguished."

I'm a little meaner with the fire and the burnings though... I use a cumulative damage modifier based on the number of rounds you've been burning; I otherwise leave the rest of the rules intact and unchanged.

  • Round 1: 1d10
  • Round 2: 1d10+1
  • Round 3: 1d10+3
  • Round 4: 1d10+6
  • Round 5+: 1d10+10

Death by immolation is a terrible thing; and the longer you're on fire, the more of you will typically be on fire.

Thank you for your comments on the rules, i believe i will apply them.

Good Quality Firebombs must be pretty popular in your games.

I'd advise against using the houserule. With the combined WP and AG test, fire already is insanely lethal.

Actually, not as much as you would think. They generally self-moderate themselves to avoid incurring such unpleasantness upon themselves. It doesn't always work in their favor, but I tend to be a touch gentler for it.

Ah, i didn't mean the house rules(though i do like them!). I meant to thank you all for showing me the stuff about flame weapons in general (which we have not been playing with correctly up to this point).
