Door Week: Bars & Doors in DF

If you're muscling through a door in GURPS Dungeon Fantasy, you sometimes have to deal with barred or wedged doors.

When this happens, you roll your contest for Forcing (DF2, p. 8) vs. the higher of the HP of the lock/hinge or bar/wedge with a penalty equal to the higher DR of the lock/hinge or bar/wedge. At least the way I do forcing rolls, it's effectively rolling against DR+HP - plus it's an easy way to visualize something like roll at -3 vs. 14 or roll at -24 vs. 46 as one number.

In any case, you only really benefit from a bar or wedge if the door's DR and/or HP is lower than that of the bar/wedge.

I totally wasted a huge amount of time on this, so hopefully it helps someone. I'll probably use this to make some simplified bar bonuses. I didn't really feel like hand-coding such a long table so I let Blogger do it - hopefully it's readable. It's a look at combos of doors and bars, and the total of higher DR + higher HP.

X-Heavy Average 12 23 35 35
X-Heavy Heavy 12 23 35 35
X-Heavy X-Heavy 12 30 42 35
X-Heavy Vault 16 37 53 35
Vault Light 24 46 70 70
Vault Average 24 46 70 70
Vault Heavy 24 46 70 70
Vault X-Heavy 24 46 70 70
Vault Vault 24 46 70 70

I bolded the ones that make sense as combinations - the weaker bars and wedges just don't help really strong hinges/locks. And vault-grade bars don't help vaults, actually. Only 15 out of the 25 combinations make any sense. Don't stick a rubber door stop into a vault and think it'll make it harder to open.

  1. Can't speak for everyone, but your timing is perfect. I've been building and painting doors for my dungeon this past weekend. Hand made, they aren't as pretty as the store bought kind, but they'll work a treat with the rest of my terrain.

  2. Munchkin walks into a bar …

    Seriously, this helps make things a bit easier. I think someone who has the spare time would do well to make even easier rules.
