What is Base DM?

What is “Base DM +1” on Zozo Flashdrive - Traveller Character Sheet and where does the modifier come from please?

It says…

+1 Base DM

+1 Insufficient Armour Skill Pen

It’s been a while since I buried my head in Traveller but I think that’s saying you get a difficulty modifier of +1 (which is a penatly) on any roll because you don’t have enough skill with the armour you are wearing.

Thanks, but DM stands for Dice Modifier, not Difficulty Modifier and +1 would be a bonus.
It doesn’t seem right but thanks for your thought.

As I said I haven’t dug into Traveller in a while, sorry. Like 5 years+. Maybe someone else can help you. Good luck

Thank you Copperhamster, thanks for trying, appreciate it.

I think it’s the Vacc Suit (TL10).

I tried it on one of my characters and, if I make the Vacc Suit “active”, I get the +1 Base DM applied. Toggling it “inactive” makes the +1 set to a 0 DM (Default).

I’m not saying the DM is the right DM, I am just saying that appears to be the logic of the Vacc Suit active/inactive equipment status.

Hi Nigel,
I think you are right. The DM is not calculated correctly, but that is the intention from this rule, “Some armours have a required skill. A Traveller suffers DM-1 to all checks taken in the armour per missing skill level. For example, a Traveller with Vacc Suit skill 0 who is in a suit that requires Vacc Suit 2 would have DM-2 to all their checks. Not having the skill at all inflicts the usual DM-3 unskilled penalty instead.”
There should not be a positive DM. I will try to find a forum to report this. Thank you for your help.
